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. 1-Methyl-1,2-ethanedithiol 1,2-Dimercaptopropane 1,2-Dithiolpropane 1,2-Propanedithiol-propylene dimercaptan 2,3-Dimercaptopropane Dithiopropylene glycol FEMA 3520 Propane-1,2-dithiol Propylene dithioglycol C3H8S2 108.226 108.006741636 propane-1,2-dithiol 1,2-propanedithiol 814-67-5 CC(S)CS InChI=1S/C3H8S2/c1-3(5)2-4/h3-5H,2H2,1H3 YGKHJWTVMIMEPQ-UHFFFAOYSA-N belongs to the class of organic compounds known as alkylthiols.
