Toxicology and carcinogenesis studies of p-chloro-α,α,α-trifluorotoluene in Sprague Dawley (Hsd:Sprague Dawley SD) rats and B6C3F1/N mice (inhalation studies)

p-Chloro-α,α,α-trifluorotoluene is a solvent used in paints and coatings and as an industrial intermediate in the production of other chemicals (e.g., herbicides, dyes, pharmaceuticals). p-Chloro-α,α,α-trifluorotoluene was nominated for study by the National Cancer Institute and Kowa American Corporation for study because of its high import volume and lack of occupational exposure limits. Male and female Hsd:Sprague Dawley SD rats and B6C3F1/N mice were exposed to p-chloro-α,α,α-trifluorotoluene (purity greater than 99.5%) by inhalation for 3 months or 2 years. Genetic toxicology studies were conducted in Salmonella typhimurium, Escherichia coli, and rat and mouse peripheral blood erythrocytes. (Abstract Abridged).
