Benzotriazole (BTA) is applied as anti-rusting agent or corrosion inhibitor for metal (mainly copper and its alloys) by forming a passive layer,
consisting of a complex between copper and benzotriazole, when copper is immersed in a solution
containing benzotriazole. The passive layer is insoluble in aqueous and many organic solutions.
Also used as anti-freezing agent for car, synthetic detergent, anti-dust agent for photography and polymer stabilizer.
