1,3-Dichloropropan-2-ol (1,3-DCP) is a chemical compound in the class of chloropropanols. It is used as a solvent and in the manufacture of some paints, lacquers, and photographic materials[2] as well as being an intermediate in the production of epichlorohydrin.[3]
1,3-DCP is a believed to be a carcinogen and mutagen.[2][4] The International Agency for Research on Cancer classifies it as a Group 2B carcinogen ("possibly carcinogenic to humans").[5]
Along with 3-monochloropropane-1,2-diol (3-MCPD), 1,3-DCP is found in some Asian style sauces such as soy sauce and oyster sauce.[6][7][8]
