Uses:

1,2,3-Benzotriazole is used as an antirust of metals, such as silver, copper, lead, nickel, and zinc. This benzotriazole is widely used for products of slushing oil (grease), mainly for vapor phase corrosion inhibitors of copper or copper alloy.

1,2,3-Benzotriazole is used as a treating compound of cycle water, antifreeze for auto, fog preventative for taking pictures, macromolecule stabilizer, ethylene chlorohydrin, lube oil additive, and ultraviolet absorber.

Benzotriazole can also be used with many dirty-resistance agents and sterilized algaecide, especially for the corrosion mitigation effect of the air proofing circulation cooling water system.
