CAS Number: 29385-43-1

Tolyltriazole (TTA) is a heterocyclic metal deactivator and corrosion inhibitor widely used in lubricants, coolants, and fuels to protect copper, brass, bronze, and other non-ferrous metals. TTA forms a stable protective coordination complex on copper surfaces, blocking oxidative attack and preventing catalytic pro-oxidation by dissolved copper ions. It is an essential component in engine oils, hydraulic fluids, automatic transmission fluids, and water-based metalworking fluids containing mixed metal components.
