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.

Refractive index = 1.531-1.541
