3-Methoxyeticyclidine (3-MeO-PCE), also known as methoxieticyclidine, is a dissociative anesthetic that is qualitatively similar to PCE and PCP and has been sold online as a designer drug.On October 18, 2012 the Advisory Council on the Misuse of Drugs in the United Kingdom released a report about methoxetamine, saying that the "harms of methoxetamine are commensurate with Class B of the Misuse of Drugs Act (1971)", despite the fact that the act does not classify drugs based on harm. The report went on to suggest that all analogues of methoxetamine should also become class B drugs and suggested a catch-all clause covering both existing and unresearched arylcyclohexamines, including 3-MeO-PCE.This report also described the receptor binding profile of Methoxetamine and three additional dissociatives 3-MeO-PCP, 4-MeO-PCP and 3-MeO-PCE, showing them to have significant affinity for the PCP site of NMDAR and was later published in more detail.3-MeO-PCE has Ki values of 61 nM for the NMDA receptor, 115 nM for the serotonin transporter, 4519 nM for the σ1 receptor and 525 nM for the σ2 receptor.

3-Methoxy-4-methylamphetamine (MMA) is an entactogen and psychedelic drug of the phenethylamine and amphetamine classes. It was first synthesized in 1970 and was encountered as a street drug in Italy in the same decade. MMA was largely forgotten until being reassayed by David E. Nichols as a non-neurotoxic MDMA analogue in 1991, and has subsequently been sold as a designer drug on the internet since the late 2000s (decade).In animal studies, MMA fully substitutes for MDMA and MBDB, partially substitutes for LSD, and does not substitute for amphetamine. Additionally, it has been shown to potently inhibit the reuptake of serotonin and does not produce serotonergic neurotoxicity in rodents. These data appear to confer a profile of MMA as a selective serotonin releasing agent (SSRA) and 5-HT2A receptor agonist.At high doses, such as 120 mg, the effects are psychedelic (comparable to DOM).

3-Methylfentanyl (3-MF, mefentanyl) is an opioid analgesic that is an analog of fentanyl. 3-Methylfentanyl is one of the most potent drugs that has been widely sold on the black market, estimated to be between 400 and 6000 times stronger than morphine, depending on which isomer is used (with the cis isomers being the more potent ones).3-Methylfentanyl was first discovered in 1974 and subsequently appeared on the street as an alternative to the clandestinely produced fentanyl analog α-methylfentanyl. However, it quickly became apparent that 3-methylfentanyl was much more potent than α-methylfentanyl, and correspondingly even more dangerous.While 3-methylfentanyl was initially sold on the black market for only a short time between 1984 and 1985, its high potency made it an attractive target to clandestine drug producers, as racemic 3-MF is 10–15 times more potent than fentanyl, and so correspondingly larger amounts of cut product for street sales can be produced for an equivalent amount of effort as for producing fentanyl itself; one gram of 3-methylfentanyl might be sufficient to produce several thousand dosage units once diluted for sale. 3-MF has thus reappeared several times, at various places around the world.The only country in the world with significant (200+ deaths a year, more than 10 000 addicts) abuse of this chemical is Estonia, where a dose of 3-MF costs 10 €, and other opiates are not generally available. Approximately 1100 deaths from fentanyl and 3-MF abuse were recorded in Estonia between 2005-2013, compared to approximately 450 deaths in Sweden, Germany, UK, Finland and Greece combined during the same period.Other opioid analogs even more potent still than 3-MF are known, such as carfentanil and ohmefentanyl, but these are significantly more difficult to manufacture than 3-methylfentanyl and have not been so well accepted as street drugs.3-Methylfentanyl has similar effects to fentanyl, but is far more potent due to increased binding affinity to its target site. Since fentanyl itself is already highly potent, 3-methylfentanyl is extremely dangerous when used recreationally, and has resulted in many deaths among recreational opioid users ingesting the drug. Side effects of fentanyl analogs are similar to those of fentanyl itself, which include itching, nausea and potentially serious respiratory depression, which can be life-threatening. Fentanyl analogs have killed hundreds of people throughout Europe and the former Soviet republics since the most recent resurgence in use began in Estonia in the early 2000s, and novel derivatives continue to appear.

3-Methylphenethylamine (3MPEA) is an organic compound with the chemical formula of C9H13N. 3MPEA is a human trace amine associated receptor 1 (TAAR1) agonist, a property which it shares with its monomethylated phenethylamine isomers, such as amphetamine (α-methylphenethylamine), β-methylphenethylamine, and N-methylphenethylamine (a trace amine).Very little data, even on toxicity, is available about its effects on humans other than that it is corrosive and activates the human TAAR1 receptor.

3-Hydroxyvalerate

The 3-Hydroxypropionate bicycle, also known as the 3-Hydroxypropionate pathway, is a process that allows some bacteria to generate 3-Hydroxypropionate utilizing carbon dioxide. In this pathway CO2 is fixed (i.e. incorporated) by the action of two enzymes, acetyl-CoA carboxylase and propionyl-CoA carboxylase. These enzymes generate malonyl-CoA and (S)-methylmalonyl-CoA, respectively. Malonyl-CoA, in a series of reactions is further split into acetyl-CoA and glyoxylate.

3-Iodothyronamine (T1AM) is an endogenous thyronamine. T1AM is a high-affinity ligand for the trace amine-associated receptor TAAR1 (TAR1, TA1), a recently discovered G protein-coupled receptor. T1AM is the most potent endogenous TAAR1 agonist yet discovered. Activation of TAAR1 by T1AM results in the production of large amounts of cAMP. This effect is coupled with decreased body temperature and cardiac output. Wu et al. have pointed out that this relationship is not typical of the endocrine system, indicating that TAAR1 activity may not be coupled to G-proteins in some tissues, or that T1AM may interact with other receptor subtypes.T1AM may be part of a signaling pathway to modulate cardiac function, as the compound can induce negative inotropic effects and decrease cardiac output.

3-in-One Oil is a general-purpose lubricating oil sold for household and do-it-yourself use. It was originally formulated in 1894 for use on bicycles, and remains a popular lubricant for their chains. Its name, given by inventor George W. Cole of New Jersey in 1894, reflects the product's triple ability to "clean, lubricate and protect". The formula consists of pale spindle oil with a small amount of corrosion inhibitor and citronella oil (which gives the product its distinctive sharp odor).The product changed ownership many times throughout the 20th century and was bought by its current owners, the WD-40 Company, in 1995. The current marketing slogan is "The Tool Kit In A Can," with the logo of the text "3 in" inside a large numeral "1".A few other products are now produced under the 3-in-1 brand, including a white lithium grease, silicone spray, and oil with added PTFE.In 2000, the can was redesigned to look like the early 20th century oil can design (hemisphere base with tapered straight spout).An advertisement found in "The Church Standard" magazine (April 13, 1901, pg. 867) offers 3 in 1 Oil as a perfect polish for pianos. It claimed that the oil was "long lasting" and did not come off on the clothes.

As a byproduct of this process, chloride can react with the glycerol backbone of lipids to produce 3-MCPD. 3-MCPD can also occur in foods which have been in contact with materials containing epichlorohydrin-based wet-strength resins which are used in the production of some tea bags and sausage casings.In 2009, 3-MCPD was found in some East Asian and Southeast Asian sauces such as oyster sauce, Hoisin sauce, and soy sauce. Using hydrochloric acid rather than traditional slow fermentation is a far cheaper and faster method but unavoidably creates chloropropanols. A 2013 European Food Safety Authority report indicated margarine, vegetable oils (excluding walnut oil), preserved meats, bread, and fine bakery wares as major sources in Europe.3-MCPD can also be found in many paper products treated with polyamidoamine-epichlorohydrin wet-strength resins.

The 3-Hydroxypropionate bicycle, also known as the 3-Hydroxypropionate pathway, is a process that allows some bacteria to generate 3-Hydroxypropionate utilizing carbon dioxide. In this pathway CO2 is fixed (i.e. incorporated) by the action of two enzymes, acetyl-CoA carboxylase and propionyl-CoA carboxylase. These enzymes generate malonyl-CoA and (S)-methylmalonyl-CoA, respectively. Malonyl-CoA, in a series of reactions is further split into acetyl-CoA and glyoxylate. Glyoxylate is incorporated into beta-methylmalyl-coA which is then split, again through a series of reactions to release pyruvate as well as acetate, which is used to replenish the cycle. This pathway has been demonstrated in Chloroflexus, a nonsulfur photosynthetic bacterium, however other studies suggest that 3-hydroxypropionate bicycle is utilized by several chemotrophic archaea.

meta-Methoxyamphetamine (MMA), also known as 3-methoxyamphetamine (3-MA), is a stimulant drug from the amphetamine family. It has similar effects in animal drug discrimination tests to the more widely known derivative 4-methoxyamphetamine (PMA), although with a slightly different ratio of monoamine release, being a combined serotonin, dopamine, and norepinephrine releasing agent rather than a fairly selective serotonin releaser like PMA. 3-Methoxyamphetamine has similarly appeared on the illicit market as a designer drug alternative to MDMA, although far more rarely than its infamous positional isomer. It produces gepefrine, a cardiac stimulant, as one of its major metabolites.

3-Hydroxyisobutyric acid (or 3-hydroxy-2-methylpropanoic acid) is an intermediate in the metabolism of valine.– It is a chiral compound having two enantiomers, D-3-hydroxyisobutyric acid and L-3-hydroxyisobutyric acid.

3-Methylbutanoic acid, also known as β-methylbutyric acid or more commonly isovaleric acid, is an organic compound with the formula (CH3)2CHCH2CO2H. It is sometimes classified as a fatty acid. It is a colourless liquid that is sparingly soluble in water, but highly soluble in most common organic solvents. The compound occurs naturally, including in essential oils.Isovaleric acid has a strong pungent cheesy or sweaty smell, but its volatile esters have pleasing scents and are used widely in perfumery. It has been proposed that it is the anticonvulsant agent in valerian. It is a major component of the cause of unpleasant foot odor, as it is produced by skin bacteria metabolizing leucine. Humans and animals produce isovaleric acid from leucine via alpha-ketoisocaproate.Isovaleric acid is seen as the primary cause of the flavors added to wine caused by Brettanomyces yeasts. Other compounds produced by Brettanomyces yeasts include 4-ethylphenol, 4-vinylphenol, and 4-ethylguaiacol. An excess of isovaleric acid in wine is generally seen as a defect, as it can smell sweaty, leathery, or like a barnyard, but in small amounts it can smell smokey, spicy, or medicinal. These phenomena may be prevented by killing any Brettanomyces yeasts, such as by sterile filtration, by the addition of relatively large quantities of sulfur dioxide and sometimes sorbic acid, by mixing in alcoholic spirit to give a fortified wine of sufficient strength to kill all yeast and bacteria, or by pasteurization. Isovaleric acid can also be found in beer, and, excepting some English–style ales, is usually considered a flaw. It can be produced by the oxidation of hop resins, or by Brettanomyces yeasts present.

3-Methyl-thiofentanyl is an opioid analgesic and analogue of fentanyl.3-Methyl-thiofentanyl was sold briefly on the black market in the early 1980s, before the introduction of the Federal Analog Act which for the first time attempted to control entire families of drugs based on their structural similarity rather than scheduling each drug individually as they appeared.3-Methyl-thiofentanyl has similar effects to fentanyl. Side effects of fentanyl analogs are similar to those of fentanyl itself, which include itching, nausea and potentially serious respiratory depression, which can be life-threatening. Fentanyl analogs have killed hundreds of people throughout Europe and the former Soviet republics since the most recent resurgence in use began in Estonia in the early 2000s, and novel derivatives continue to appear.

3-Hydroxymorphinan (3-HM), or morphinan-3-ol, is a psychoactive drug of the morphinan family. It is the racemic counterpart to norlevorphanol.The dextrorotatory stereoisomer of the compound is an active metabolite of dextromethorphan, dextrorphan, and 3-methoxymorphinan, and similarly to them has potent neuroprotective and neurotrophic effects on LTS- and MPTP-treated dopaminergic neurons of the nigrostriatal pathway, but notably without producing any neuropsychotoxic side effects (e.g., dissociation or hallucinations) or having any anticonvulsant actions. It does not seem to bind to the NMDA receptor, and instead, its neuroprotective properties appear result from inhibition of glutamate release via the suppression of presynaptic voltage-dependent Ca2+ entry and protein kinase C activity. In any case, as such, the compound has been investigated as a potential antiparkinsonian agent. A prodrug, GCC1290K, has been developed on account of 3-HM's poor bioavailability (18%), and a New Drug Application has been approved for it by the United States Food and Drug Administration. It is currently undergoing clinical trials for the treatment of Parkinson's disease. It does not have a Controlled Substances Act 1970 schedule, ACSCN, or annual aggregate manufacturing quota and may not necessarily be controlled, whilst norlevorphanol is; none of the dextrorotary derivatives of the dromoran and norlevorphanol sub-families of morphinan derivatives are controlled as they do not have opioid activity but the other racemic compounds are.3-HM's levorotatory stereoisomer, norlevorphanol, in contrast to (+)-3-HM, is an opioid analgesic. It was never marketed as such however, probably due to a combination of the facts that norlevorphanol has low bioavailability and that its potency is diminished compared to its N-methylated analogue levorphanol.
