The draft Toxicological Review of 1,2,3-Trichloropropane provides scientific support and rationale for the hazard identification and dose-response assessment pertaining to chronic exposure to 1,2,3-trichloropropane. 1,2,3-Trichloropropane is an important industrial chemical used as a solvent for oils and fats, waxes, and resins, and has also been used in paint thinner and varnish remover and as a degreasing agent. 1,2,3-Trichloropropane is also generated as a by-product of the production of other chlorinated compounds such as epichlorohydrin, and is used as an intermediate in the production of some pesticides and polymers, such as polysulfide rubbers.
This assessment contains the derivation of a chronic reference dose and a chronic reference concentration, as well as a cancer characterization and the derivation of an oral slope factor.
