1H-Benzotriazole (CAS 95-14-7) is a heterocyclic organic compound available as white needle-like crystals or granules, primarily utilized as a high-performance corrosion inhibitor for copper and its alloys in cooling water systems, antifreeze fluids, and industrial lubricants. This 1,2,3-Benzotriazole compound functions as a potent metal deactivator by forming a thin, insoluble protective film on metal surfaces in Benzotriazole treated systems, effectively preventing galvanic corrosion and oxidative tarnish in atmospheric and aqueous environments. To support industrial-scale requirements, we provide bulk supply with competitive factory pricing and ensure rigorous quality control through customized specifications alongside standard technical documentation, including MSDS, TDS, COA.

FAQ - Technical & Supply Chain
-
Q:
Is 1H-Benzotriazole (CAS 95-14-7) suitable for use in multi-metal systems?
A: Yes, while it specifically targets copper and brass, its protective film formation (C6H5N3) benefits the entire system by reducing the release of copper ions that could otherwise plate out on and corrode steel or aluminum components. -
Q:
What is the difference between BTA and Tolyltriazole (TTA)?
A: BTA is the pure unsubstituted parent compound, often preferred for its higher purity and specific film stability in pharmaceutical or fine chemical applications, whereas TTA is a methylated derivative typically used as a lower-cost alternative in bulk industrial water treatment.
