C3H8S2

C3H8S2 refers to 1,3-propanedithiol, also known as propanedithiol. The molecule is an organosulfur compound with a linear three-carbon chain bearing thiol groups at both ends, written as HS-CH2-CH2-CH2-SH. As a bifunctional dithiol, it is a useful building block in organic synthesis and coordination chemistry.

Physically, propanedithiol is typically a colorless to pale yellow liquid at room temperature and has a strong, characteristic odor typical of thiols. It is reactive toward oxidation, readily forming the corresponding disulfide upon exposure to air or oxidants. In metal complexes, the two thiol groups can bind to a single metal center, acting as a bidentate ligand in suitable contexts.

Applications and uses of propanedithiol include serving as a versatile precursor for the synthesis of thioether and thioester derivatives, as well as a bifunctional crosslinker in polymer chemistry. It is employed as a reagent in organic synthesis and can be used to prepare various sulfur-containing compounds and coordination compounds with metal ions.

Safety and handling guidance follow standard practices for low-molecular-weight thiols. Propanedithiol has a strong, persistent odor and can be irritating to skin, eyes, and the respiratory tract. It is flammable and should be used in a well-ventilated area with appropriate personal protective equipment. Storage and disposal should comply with applicable regulations and the safety data sheet (SDS).
