# 1,2-Propanedithiol

1,2-Propanedithiol, sometimes called 1,2-dimercaptopropane, is a thiol with the formula $HSCH_2CH(SH)CH_3.$ This colorless, intensely odorous liquid is the simplest chiral dithiol. Related dithiols include 1,2-ethanedithiol, 2,3-dimercapto-1-propanesulfonic acid, and 1,3-propanedithiol. It is generated by the addition of $H_2S$ to the related episulfide, $CH_3CHCH_2S.$
