Chemical formula or substitute for benzotriazole


You asked to use benzotriazole for preventing copper from oxidation and also increase its glare. Can you give its chemical formula as it is not readily available in the market, else give its substitute.

Our Laser HFP is a triazole based copper anti-tarnish that is available for export.

But benzotriazole is readily available; ask your chemical supplier for an anti-tarnish. Citric acid is also used for this purpose.
