Benzotriazoles are a class of organic compounds characterized by a benzotriazole ring system. This system consists of a benzene ring fused to a triazole ring, which is a five-membered heterocyclic ring containing three nitrogen atoms. The chemical formula for benzotriazole itself is C6H5N3.

Benzotriazoles are known for their chelating properties, meaning they can form stable complexes with various metal ions. This characteristic makes them useful in several industrial applications. For example, they are widely employed as corrosion inhibitors for copper and its alloys, preventing tarnishing and degradation. They are also utilized in photographic emulsions, antifreeze formulations, and as UV stabilizers in plastics and coatings.

The synthesis of benzotriazoles typically involves the reaction of an ortho-phenylenediamine derivative with nitrous acid. Depending on the starting materials and reaction conditions, various substituted benzotriazoles can be produced, each with potentially different properties and applications.

While generally considered to have low toxicity, some benzotriazole derivatives can be persistent in the environment. Their widespread use in consumer products and industrial processes has led to their detection in wastewater and natural water bodies, prompting ongoing research into their environmental fate and potential ecological impacts.
