The assessment of o-toluidine for potential carcinogenicity is based on data from studies using o-toluidine hydrochloride, since o-toluidine is rapidly and completely converted to the hydrochloride after oral ingestion. Therefore, this profile summarizes the relevant cancer literature on o-toluidine hydrochloride. o-Toluidine is a potential human carcinogen, classified as weight-of-evidence Group B2 under the EPA Guidelines for Carcinogen Risk Assessment. Evidence on potential carcinogenicity from animal studies is 'Sufficient', and the evidence from human studies is 'Inadequate'. The potentcy factor (F) for o-toluidine is estimated to be 0.069 (mg/kg/day)-1, placing it in potency group 3 according to the CAG's methodology for evaluating potential carcinogens. Combining the weight-of-evidence group and the potency group, o-toluidine is assigned a 'LOW' hazard ranking.
