Three structurally related compounds, 4-chloro-o-phenylenediamine (COP), 4-nitro-o-phenylenediamine (NOP) and p-phenylenediamine dihydrochloride (PPD), are used in fur dyes, inks and hair coloring formulations. COP has been reported to be carcinogenic in both rats and mice. NOP and PPD are non-carcinogens, but

Three pairs of structurally similar carcinogenic/non-carcinogenic chemicals were tested for in vivo genotoxic activity in B6C3F1 mice. The carcinogenic/non-carcinogenic pairs, respectively, were o-toluidine hydrochloride/o-anthranilic acid, 4-chloro-o-phenylenediamine/4-nitro-o-phenylenediamine, and 3-(chloromethyl)pyridine hydrochloride/2-(chloromethyl)pyridine hydrochloride.
