Request SDS →Benzotriazole (CAS 95-14-7) is a nitrogen heterocycle used primarily as a corrosion inhibitor for copper and copper alloys. It protects metal in recirculating water-cooling systems, metalworking fluids, and antifreeze, and also serves as a chemical intermediate and a tarnish-preventing surface treatment.
Frequently Asked Questions
What is benzotriazole (BTA) also known as?
1,2,3-Benzotriazole (CAS 95-14-7) is also referred to as BTA and 1H-benzotriazole. It is a nitrogen heterocycle used primarily as a corrosion inhibitor for copper and copper alloys.
What is benzotriazole used for?
Its primary use is as a corrosion inhibitor that passivates copper and copper alloys in recirculating water-cooling systems, metalworking fluids, and antifreeze. It also serves as a chemical intermediate (for derivatives such as tolyltriazole), a tarnish-preventing surface treatment, and a restrainer in photographic processing.
What is an alternative to benzotriazole?
Tolyltriazole (TTA) is a closely related triazole used for copper-corrosion inhibition where a methylated derivative is preferred. Selection between BTA and TTA depends on the formulation and system requirements; benzotriazole itself is supplied under CAS 95-14-7.
Is benzotriazole soluble in water?
Benzotriazole has limited water solubility that increases with temperature, and it is more readily soluble in many organic solvents. Consult the technical data sheet for solubility figures relevant to your formulation.
What is the bulk price of benzotriazole and is an SDS available?
An SDS and CoA are provided with bulk orders. It is classified under HS 2933.99; submit a bulk RFQ with your target volume and packaging for current pricing.
