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]
