1,3-Dichloropropan-2-ol (1,3-DCP) is an organic compound with the formula HOCH2CHClCH2Cl. It is a colorless liquid. It is an intermediate in the production of epichlorohydrin.[2][3]
1,3-DCP is a believed to be a carcinogen and mutagen.[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]
