The chemical compound 1,2-dioxetanedione, or 1,2-dioxacyclobutane-3,4-dione, often called peroxyacid ester, is an unstable oxide of carbon (an oxocarbon) with formula C2O4. It can be viewed as a double ketone of 1,2-dioxetane (1,2-dioxacyclobutane), or a cyclic dimer of carbon dioxide.In ordinary conditions, it quickly decomposes to carbon dioxide (CO2) even at 180 K (−93 °C), but can be detected by mass spectrometry and other techniques.1,2-Dioxetanedione is an intermediate in the chemoluminescent reactions used in glowsticks. The decomposition proceeds via a paramagnetic oxalate biradical intermediate.Recently it has been found that a high-energy intermediate in one of these reactions (between oxalyl chloride and hydrogen peroxide in ethyl acetate), which is presumed to be 1,2-dioxetanedione, can accumulate in solution at room temperature (up to a few micromoles at least), provided that the activating dye and all traces of metals and other reducing agents are removed from the system, and the reactions are carried out in an inert atmosphere.

1,2,4-Trioxane is one of the isomers of trioxane. It has the molecular formula C3H6O3 and consists of a six membered ring with three carbon atoms and three oxygen atoms. The two adjacent oxygen atoms form a peroxide functional group and the other forms an ether functional group. It is like a cyclic acetal but with one of the oxygen atoms in the acetal group being replaced by a peroxide group.1,2,4-Trioxane itself has not been isolated or characterized, but rather only studied computationally. However, it constitutes an important structural element of some more complex organic compounds. The natural compound artemisinin, isolated from the sweet wormwood plant (Artemisia annua), and some semi-synthetic derivatives are important antimalarial drugs containing the 1,2,4-trioxane ring. Completely synthetic analogs containing the 1,2,4-trioxane ring are important potential improvements over the naturally derived artemisinins. The peroxide group in the 1,2,4-trioxane core of artemisinin is cleaved in the presence of the malaria parasite leading to reactive oxygen radicals that are damaging to the parasite.

1,2-Dichlorotetrafluoroethane, or R-114, also known as cryofluorane (INN), is a chlorofluorocarbon (CFC) with the molecular formula ClF2CCF2Cl. Its primary use has been as a refrigerant. It is a non-flammable gas with a sweetish, chloroform-like odor with the critical point occurring at 145.6 °C and 3.26 MPa. When pressurized or cooled, it is a colorless liquid. It is listed on the Intergovernmental Panel on Climate Change's list of ozone depleting chemicals, and is classified as a Montreal Protocol Class I, group 1 ozone depleting substance.When used as a refrigerant, R-114 is classified as a medium pressure refrigerant.The US Navy uses R-114 in its centrifugal chillers in preference to R-11 to avoid air and moisture leakage into the system. While the evaporator of an R-11 charged chiller runs at a vacuum during operation, R-114 yields approximately 0 psig operating pressure in the evaporator.

1,2-Bis(dicyanomethylene)squarate is a divalent anion with chemical formula C10N4O2−2 or ((N≡C−)2C=)2(C4O2)2−. It is one of the pseudo-oxocarbon anions, as it can be described as a derivative of the squarate oxocarbon anion C4O2−4 through the replacement of two adjacent oxygen atoms by dicyanomethylene groups =C(−C≡N)2.The anion can be obtained by reacting squaric acid with n-butanol to obtain the diester 1,2-dibutyl squarate (an oily orange liquid) and treating the latter with metallic sodium and malononitrile (N≡C−)2CH2 to give the trihydrated disodium salt 2Na+·C10N4O2−2·3H2O, a yellow water-soluble solid. The hydrated salt loses the water below 100 °C, but the resulting anhydrous salt is stable up to 400 °C. Reaction of the sodium salt with the chlorides of other cations in ethanol affords the following salts:dipotassium 2K+·K2C10N4O2−2, anhydrous, yellow, stable to 300 °Cdirubidium 2Rb+·Rb2C10N4O2−2, anhydrous, brown, stable to 300 °Cmagnesium sodium chloride, Mg2+·Na+·Cl−·C10N4O2−2· 4 1⁄2H2O, dark yellow, dehydrates at 60–106 °C, stable to 461 °Ccalcium disodium, 2Na+·Ca2+·2C10N4O2−2·9H2O, yellow, dehydrates at 50–90 °C, stable to 178 °Cbarium, Ba2+·C10N4O2−2·2H2O, yellow, dehydrates at 87 °C, stable to 337 °Ctetra-n-butylammonium, 2(C4H5)4N+·C10N4O2−2·H2O, yellow, dehydrates at 145 °C, stable to 323 °CNuclear magnetic resonance shows that the aromatic character of the squarate core is retained.

1,2,4-Butanetriol is a clear or slightly yellow, odorless, hygroscopic, flammable, viscous liquid. It is an alcohol with three hydrophilic alcoholic hydroxyl groups. It is similar to glycerol and erythritol. It is chiral, with two possible enantiomers.1,2,4-Butanetriol is used in the manufacture of butanetriol trinitrate (BTTN), an important military propellant.1,2,4-Butanetriol is also used as a precursor for two cholesterol-lowering drugs, Crestor and Zetia, which are derived from D-3,4-dihydroxybutanoic acid, by using 3-hydroxy-gamma-butyrolactone as a chiral synthon Niu, W (2003).

It is as one of the monomers for manufacture of some polyesters and as a solvent.1,2,4-Butanetriol can be prepared synthetically by several different methods such as hydroformylation of glycidol and subsequent reduction of the product, sodium borohydride reduction of esterified malic acid, or catalytic hydrogenation of malic acid. However, of an increasing importance is the biotechnological synthesis using genetically engineered Escherichia coli and Pseudomonas fragi bacteria.
