Chloropropanols are chlorohydrins related to propanols containing chloride functional group. Eight isomers are possible. Two of these derivatives, 1,3-dichloropropanol (1,3-DCP) and 3-chloropropane-1,2-diol (3-MCPD), are carcinogenic contaminants in processed foods. Several isomers are encountered in industrial chemistry.
