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