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-ethanedithiol1,2-Dimercaptopropane1,2-Dithiolpropane1,2-Propanedithiol-propylene dimercaptan2,3-DimercaptopropaneDithiopropylene glycolFEMA 3520Propane-1,2-dithiolPropylene dithioglycolC3H8S2108.226108.006741636propane-1,2-dithiol1,2-propanedithiol814-67-5CC(S)CSInChI=1S/C3H8S2/c1-3(5)2-4/h3-5H,2H2,1H3YGKHJWTVMIMEPQ-UHFFFAOYSA-N belongs to the class of organic compounds known as alkylthiols.
