Product Description
Sodium Benzotriazole, CAS 15217-42-2, is the sodium salt form associated with benzotriazole chemistry. It is used in selected industrial applications where corrosion control and the protection of metal surfaces are important. Its performance depends on the metal substrate, water chemistry, operating conditions, concentration, and the other ingredients present in the treatment system.
One relevant application area is the protection of copper and copper alloys in aqueous environments. Sodium benzotriazole may be incorporated into appropriately designed corrosion-inhibition systems for industrial water treatment, metalworking, and related maintenance applications. Its suitability should be established through compatibility testing and performance evaluation under representative operating conditions.
Commercial material may be supplied as a solid or as an aqueous solution, depending on the grade. Consequently, appearance, active content, density, solubility, and handling requirements should be taken from the actual product specification rather than assumed from the chemical name alone.
For purchasing and formulation review, confirm that the supplied material is the intended sodium salt and that its CAS number matches the batch documentation. This is especially important when distinguishing sodium benzotriazole from methyl-substituted benzotriazole derivatives, which are not automatically interchangeable. The current technical data sheet, safety data sheet, and batch certificate of analysis should define the material's identity, concentration, quality limits, and recommended storage conditions.

Product Applications
1. Copper and Copper-Alloy Corrosion Protection
Sodium benzotriazole can be evaluated in corrosion-inhibition systems intended to help protect copper and copper-containing components in suitable aqueous environments. Performance should be verified for the specific metal, water composition, temperature, and operating conditions.
2. Industrial Water Treatment
It may be considered for selected industrial water-treatment formulations where copper corrosion is a concern. The treatment program should account for water chemistry, other additives, material compatibility, and applicable discharge requirements.
3. Metalworking and Equipment Maintenance
Selected metalworking or maintenance formulations may use sodium benzotriazole as a corrosion-control ingredient. Suitability depends on the process, the metals in contact with the formulation, and the required protection period.
4. Coolant and Heat-Transfer Systems
It may be evaluated in compatible coolant or heat-transfer-fluid formulations where protection of copper-containing components is required. Confirm compatibility with the complete inhibitor package, system materials, and operating conditions before use.
5. Formulation and Laboratory Evaluation
The material can serve as a test ingredient in corrosion-inhibition studies and formulation screening. Record the exact grade, concentration, test conditions, and metal substrate so that results can be compared reliably.
FAQ
Q1: What is Sodium Benzotriazole CAS 15217-42-2?
It is a sodium salt associated with benzotriazole chemistry and is used in selected industrial applications, particularly corrosion-control systems. Confirm the precise identity against the supplier's documentation.
Q2: Is Sodium Benzotriazole the same as Sodium Methylbenzotriazole?
They should not be treated as interchangeable names. The word “methyl” indicates a methyl-substituted structure, and the corresponding substance may have a different CAS number. Verify the chemical identity before using either name.
Q3: What should buyers check before ordering?
Confirm the CAS number, chemical identity, physical form, active content or solution concentration, impurity profile, packaging, and batch-specific COA. Request the current TDS and SDS as well.
Q4: Can it be used in every water-treatment or coolant formulation?
No. Suitability depends on the system chemistry, metals present, operating conditions, formulation compatibility, and applicable requirements. Conduct appropriate compatibility and performance tests before commercial use.
