Notes:

1,2-Propanedithiol, sometimes called 1,2-dimercaptopropane, is a thiol with the formula HSCH2CH(SH)CH3. 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 H2S to the related episulfide, CH3CHCH2S.
