12heptanediol

12-Heptanediol is an organic compound with the chemical formula C7H16O2. It is a diol, meaning it contains two hydroxyl (-OH) functional groups. In this specific molecule, these two hydroxyl groups are located on the first and twelfth carbon atoms of a seven-carbon chain. This unusual arrangement, with the hydroxyl groups at the extreme ends of a very long hydrocarbon chain, gives 12-heptanediol distinct properties compared to shorter-chain diols.

The physical state of 12-heptanediol at room temperature is typically a solid or a viscous liquid, depending on its purity and ambient temperature. Due to the presence of the polar hydroxyl groups, it exhibits some solubility in polar solvents like water and ethanol, although the long nonpolar hydrocarbon chain limits its overall water solubility. It is more soluble in less polar organic solvents.

12-Heptanediol can be synthesized through various organic chemistry routes, often involving reactions that introduce hydroxyl groups onto a long-chain alkane or alkene precursor. Its specific applications are not as widely documented as those of shorter-chain diols. However, compounds with long diol structures can find use as monomers in the synthesis of specialized polymers, such as polyesters or polyurethanes, where the long chain can impart flexibility and modify material properties. They might also serve as intermediates in the synthesis of more complex organic molecules or as components in formulations where specific solvency or surface-active properties are desired. Research into its precise industrial uses and biological activity is ongoing.
