Chemical formula or substitute for benzotriazole
Q. You suggested using benzotriazole for preventing copper from oxidation and also increasing its shine. Can you give its chemical formula as it is not readily available in the market, else give its substitute.?

Q. Sir,
Can anybody suggest a cheap substitute for copper inhibitor benzotriazole?

A. Hi Akash. We added your question to a thread where James proposes citric acid as a possible substitute. It may be a satisfactory substitute in some ways for some applications, but will be wholly unsatisfactory for others. Please get back to us after you test it. Good luck.

A. Tolyltriazole is about as effective. Sometimes it is a little more expensive, sometimes a little less expensive. There is no cheap effective substitute. But if you want something cheap and accept a significant reduction in performance you could try triethanolamine or a similar compound.
