Cas no 1639-09-4 (1-Heptanethiol)
1-Heptanethiol (CAS 1639-09-4) is a linear aliphatic thiol with the molecular formula C?H??S. This clear to slightly yellow liquid is characterized by its strong, unpleasant odor, typical of mercaptans. It is sparingly soluble in water but miscible with organic solvents such as ethanol and ether. 1-Heptanethiol is primarily used as a chemical intermediate in organic synthesis, particularly in the production of surfactants, lubricant additives, and specialty polymers. Its long hydrocarbon chain and reactive thiol group make it valuable for modifying surface properties and creating sulfur-containing compounds. The compound should be handled with care due to its flammability and potential irritant effects. Storage under inert atmosphere is recommended to prevent oxidation.
