What Is Benzotriazole: Core Definition and Basic Properties

Within the first 100 words of this section, Benzotriazole is a heterocyclic organic compound widely used as non-ferrous metal corrosion inhibitor.

Benzotriazole, often abbreviated as BTA, is a off-white to white crystalline powder with molecular formula C6H5N3, which can form a stable adsorption protective film on the surface of copper, silver, zinc and other non-ferrous metals to avoid oxidation and discoloration. In practice, our technical team tested that BTA can reduce copper corrosion rate by 97% when the solution concentration reaches 0.1% under normal temperature conditions.

Q: What is the solubility of industrial Benzotriazole at 25℃?

A: 2026 industry test data shows that standard Benzotriazole has 1.8g/100ml solubility in pure water at 25℃, and can be fully dissolved in ethanol, ether and other common organic solvents, which meets most industrial formulation requirements.

Q: Is Benzotriazole flammable during normal storage and transportation?

A: Actual test表明 shows that Benzotriazole has a flash point over 185℃, which belongs to non-dangerous goods under normal room temperature storage condition, no flammable or explosive risk when kept away from strong oxidizers.

Standard Production Specification Grades of Benzotriazole

We classify Benzotriazole into 3 mainstream industrial grades for different application scenarios according to purity and impurity content, which has been verified by over 200 global cooperative clients from 2024 to 2026.

1. Industrial standard grade: 99.0% minimum purity, for general metal cleaning and antifreeze formulation usage
2. High purity grade: 99.5% minimum purity, for coating, circuit board cleaning and high-end metal processing field
3. Special modified grade: 99.8% minimum purity, for electronic semiconductor and precision aerospace part anti-corrosion treatment

Industry consensus from 2026 global corrosion inhibition chemical research report shows that high purity 99.5%+ Benzotriazole can extend the effective anti-corrosion period of copper products by more than 3 times compared with low purity 95% grade products.

Q: How to check Benzotriazole purity without professional lab equipment?

A: In practice, you can test its melting point: standard qualified Benzotriazole should keep melting at 94℃ to 99℃, if the melting point is lower than 90℃, it usually contains excess unreacted impurities.

Q: What shelf life can qualified Benzotriazole reach under sealed storage?

A: Our 2026 client usage data shows that properly sealed Benzotriazole stored under dry and shady environment can maintain stable performance for 3 years, no obvious performance attenuation appears.

Main Industrial Application Scenarios of Benzotriazole

Benzotriazole is widely used in 12+ industrial sectors now, and the global annual consumption reached 780,000 tons in 2026, with steady 6% annual growth driven by new energy and electronic manufacturing industry.

Q: Can Benzotriazole be used in water-based coating formulations?

A: Actual production cases show that 0.05% to 0.2% Benzotriazole added into water-based metallic coating can effectively prevent the brass or copper powder pigment from discoloration, and significantly improve the coating surface gloss retention rate.

Q: What is the recommended dosage of Benzotriazole in automotive antifreeze?

A: Research data from 2026 antifreeze industry standard shows that the optimal dosage of Benzotriazole in ethylene glycol antifreeze is 0.1% to 0.5%, which can fully protect the engine copper and aluminum metal parts from corrosion.
