Thin-layer chromatography of 83 p-aminoazobenzene derivatives, which include carcinogenic azo dyes and their metabolites, was carried out on Silica Gel H plates. Simple method to determine the structure of a dye was devised ; an azo dye was reduced with sodium hydrosulfite to aniline derivatives which were identified with the authentic samples on the thin-layer plates. Rf values of 46 aniline derivatives related to the azo dyes are also listed.
