Abstract

6-Amino-2-phenyl-7-chloro-2H-benzotriazole-4-carboxylic acid was prepared by oxidation of 2,5-diamino-4-chloro-2-phenylazobenzoic acid, and its diazotization and subsequent transformations of the diazo compounds were studied. 7-Hydroxy-2-phenyl-2H-benzotriazole-4-carboxylic acid was prepared.
