C12H26O2

C12H26O2 is the molecular formula of a saturated alkanediol containing 12 carbon atoms, 26 hydrogen atoms, and two oxygen atoms. The formula corresponds to diols in which the two oxygen atoms are present as hydroxyl groups, giving the class of compounds known as dodecanediols. The structure is not fixed; many isomers exist, such as 1,2-dodecanediol and 1,3-dodecanediol, among others. All isomers share a saturated carbon chain (no rings or multiple bonds), so their degree of unsaturation is zero.

Physical properties vary with isomer; as a class they are colorless solids or liquids with relatively high boiling points and low volatility for the long hydrocarbon chains. They are poorly soluble in water but soluble in many organic solvents. Molar mass is about 202.34 g/mol.

Industrial production occurs via several routes, including dihydroxylation of long-chain alkenes or related reduction procedures on fatty-chain precursors. The exact method depends on the desired isomer and application.

Uses include serving as monomers or comonomers in polyester and polyurethane production, as plasticizers, solvents, or intermediates in chemical synthesis. The properties of a given C12H26O2 isomer influence its suitability for specific applications, particularly regarding viscosity, boiling point, and compatibility with other materials.

Safety and handling follow general guidelines for diols: they are typically of relatively low volatility but can be irritants to skin, eyes, and respiratory systems. Proper protective equipment and ventilation are advised when handling concentrated samples or performing larger-scale syntheses.
