Benzotriazoles, bicyclic heterocyclic systems containing three nitrogen atoms and a fused benzene ring, show a wide range of biological and pharmacological activities as well as applications in materials science. Benzotriazole can be synthesized using benzene-1,2-diamine and carboxylic acid.

Benzotriazoles possess a wide spectrum of biological activities including. N-(2-Aminobenzoyl)benzotriazoles, prepared from anthranilic acids and containing both free amino and active carbonyl groups, are stable reagents that have been utilized as versatile intermediates for the synthesis of anthranilic acid amides, 14 esters and thioesters 15 as well as heterocycles.
