Infobox references

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

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]
