6-Amino-7-chloro-2-(2-hydroxyphenyl)-2H-benzotriazole-4-carboxylic acid and its analogs containing chlorine and nitro groups in the phenyl fragment have been synthesized. The special features of reduction and acetylation reactions with the obtained compounds have been studied. Methods have been developed for further chemical conversions which enable a large number of 2-(2-hydroxyphenyl)-2H-benzotriazole-4-carboxylic acid derivatives to be obtained, with the aim of studying the dependence of their luminescence and complex-forming properties on various functional substituents.
