(±)-3-Chloro-1,2-propanediol may be used in manufacture of dye intermediates.

Biochem/physiol Actions

3-Chloro-1,2-propanediol is a potent rodent chemosterilant.

General description

3-Chloro-1,2-propanediol undergoes enantioselective transformation to (R)-3-chloro-1,2-propanediol by the cell extract of Corynebacterium sp. strain N-1074 . It is a contaminant found in food in free (diol) form as well as in an esterified (with fatty acids) form.

During the course of the transformation of 1,3-dichloro-2-propanol (DCP) into (R)-3-chloro-1,2-propanediol [(R)-MCP] with the cell extract of Corynebacterium sp. strain N-1074, epichlorohydrin (ECH) was transiently formed. The cell extract was fractionated into two DCP-dechlorinating activities (fractions Ia and Ib) and

3-Mono-chloropropane-1,2-diol (3-MCPD) is a contaminant that occurs in food in its free (diol) form as well as in an esterified (with fatty acids) form. Using a simple intestinal model, it was demonstrated that 3-MCPD monoesters and 3-MCPD diesters are accepted

A series of twelve breast milk samples were analysed by gas chromatography-mass spectrometry (GC/MS) operated in selected ion monitoring mode for 3-chloropropane-1,2-diol (3-MCPD). Whilst none of the samples contained 3-MCPD above the limit of detection of 3 microg kg(-1) milk
