Benzotriazole (BTA), with the chemical formula C6H5N3, is a heterocyclic organic compound composed of a benzene ring fused with a 1,2,3-triazole ring. This white to light tan solid is a versatile chemical with a wide range of applications across various industries worldwide (excluding for this context), primarily due to its effective corrosion inhibition and ultraviolet (UV) stabilization properties. Its unique chemical structure allows it to form protective films on metal surfaces and absorb harmful UV radiation, making it an indispensable component in numerous industrial and consumer products.

One of the most significant global applications of benzotriazole is as a corrosion inhibitor, particularly for copper and its alloys like brass and bronze. It forms a protective, insoluble complex layer on the metal surface, preventing oxidation and corrosion in various aqueous and atmospheric environments. This property makes it crucial in applications such as industrial cooling water systems, antifreeze solutions, metalworking fluids, and…
