Benzotriazole (BTA), also known as 1H-Benzotriazole, is a heterocyclic organic compound with the molecular formula C₆H₅N₃ and CAS number 95-14-7. It consists of a benzene ring fused with a 1,2,3-triazole ring, giving it unique chelating properties toward metal surfaces — particularly copper and copper alloys.
Originally developed as a corrosion inhibitor, Benzotriazole has evolved into a multi-functional additive widely used in industrial chemistry, coatings, and polymer stabilization. It forms a tight, monomolecular protective film on metal surfaces, dramatically reducing oxidation and corrosive attack even in harsh environments.
