Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If formulated as aqueous corrosion inhibitor solution for retail
Mixtures containing benzotriazole as active ingredient for specific use like anti-freeze preparations fall under prepared chemical mixtures, not pure compounds.
If supplied as additive in anti-freeze preparations
When intentionally mixed with other substances for antifreeze use, classified as fuel additives rather than pure heterocyclic compound.
