Title: Evaluation of the potential carcinogenicity of 4,4'-methylenebis (1-chloroaniline) (101-14-4). Final report

Technical Report ·
OSTI ID:6147905

4,4'-Methylenebis(2-chloroaniline) is a probable human carcinogen, classified as weight-of-evidence Group B2 under the EPA Guidelines for Carcinogen Risk Assessment (US EPA, 1986a). Evidence on potential carcinogenicity from animal studies is Sufficient, and the evidence from human studies is Inadequate. The potency factor (F) for 4,4'-methylenebis(2-chloroaniline) is estimated to be 1.52/(mg/kg/day), placing it in potency group 2 according to the CAG's methodology for evaluating potential carcinogens (US EPA, 1986b). Combining the weight-of-evidence group and the potency group, 4,4'-methylenebis (2-chloroaniline) is assigned a MEDIUM hazard ranking for the purposes of reportable quantity (RQ) adjustment.
