Plant Activation of Bicyclic Aromatic Amines, Benzidine and 4-Aminobiphenyl
Bicyclic aromatic amines, benzidine and 4-aminobiphenyl (4-ABP) have been known as human bladder carcinogens and used in industrial manufacturing. Using the plant cell/microbe coincubation assay, this study showed that benzidine and 4-ABP were activated by plant peroxidase into frameshift- and base …

Preparation of Immunogens and Antisera Monitoring for Eventual Radioimmunoassay Development of Benzidine.
Benzidine-based dyes have been evaluated by the National Institute for Occupational Safety and Health and determined to be potential human carcinogens. Several studies show that benzidine-based dyes are associated with animal disease states and human bladder cancer.

Aqueous reactions of ozone with primary aromatic amines
… nitrobenzenes, azobenzenes, azoxybenzenes, benzidines, aminodiphenylamines, and phenazines. The N-substituted polyaromatic compounds (NPACs), azobenzenes, azoxybenzenes, and benzidines, were the products of interest because of their potential toxicity. When the reactions were conducted under …
