Description and Uses
p-Aminodiphenylamine hydrochloride was formerly used as a hair dye. Sensitization, when deteeted by patch testing, is relatively low in hairdressers.
4-Aminodiphenylamine is used as an oxidation dye color in hair dyes. It is also promoted as an efficient reagent for oxidase enzymes, including glucose, lactate, xanthine, and lysine oxidases.
