Supplement 7: (1987) (p. 126)

CAS No.: 98-88-4

A. Evidence for carcinogenicity to humans (inadequate)

Six cases of respiratory cancer were reported among workers in two small factories where benzoyl chloride and its chlorinated precursors were produced [ref: 1].

B. Evidence for carcinogenicity to animals (inadequate)

Benzoyl chloride was tested in two sets of experiments by skin application to female mice. A few skin carcinomas were observed, but their incidence was not statistically significant [ref: 1].

C. Other relevant data

No data were available on the genetic and related effects of benzoyl chloride in humans. It did not induce mutation or DNA damage in bacteria [ref: 2].

Overall evaluation

Benzoyl chloride is not classifiable as to its carcinogenicity to humans (Group 3).
