1,4-Butanedithiol is an organosulfur compound with the formula HSCH₂CH₂CH₂CH₂SH. It is a malodorous, colorless liquid that is highly soluble in organic solvents. The compound has found applications in biodegradable polymers.^[2]

Reactions[edit]

Alkylation with geminal dihalides gives 1,3-dithiepanes. Oxidation gives the cyclic disulfide 1,2-dithiane:^[3]

HSCH₂CH₂CH₂CH₂SH + O → S₂(CH₂)₄ + H₂O

It forms self-assembled monolayers on gold.^[4]

It is also used in polyadditions along with 1,4-butanediol to form sulfur-containing polyester and polyurethanes containing diisocyanate.^[5]^[6]^[7] Several of these polymers are considered biodegradable and many of their components are sourced from non-petroleum oils.^[8]
