12dodecanediol

12-dodecanediol is a long-chain diol with the chemical formula HO(CH2)12OH. It is a white crystalline solid at room temperature. This compound is characterized by two hydroxyl (-OH) groups located at the terminal positions of a twelve-carbon alkane chain. The presence of these hydroxyl groups makes 12-dodecanediol polar, while the long hydrocarbon chain imparts some hydrophobic character.

12-dodecanediol can be synthesized through various chemical routes, often involving the reduction of corresponding dicarboxylic acids or diesters. It is an important intermediate in the production of polymers, particularly polyesters and polyurethanes, where its difunctional nature allows for chain extension and crosslinking. It can also be used in the formulation of personal care products, lubricants, and as a building block for specialty chemicals. Its physical properties, such as its melting point and solubility, are influenced by its molecular structure. The relatively long hydrocarbon chain contributes to a higher melting point compared to shorter-chain diols.
