Description

Nitrite CAS NO 14797-65-0 is an inorganic salt widely recognized for its role as a versatile chemical intermediate and corrosion inhibitor. Its primary commercial value lies in its ability to form protective oxide layers on metal surfaces, preventing rust and degradation in industrial systems. This product is essential for manufacturers and service providers in the water treatment, metal finishing, and heat transfer fluid industries seeking reliable, cost-effective corrosion control solutions.

Application

• Corrosion Inhibitor in closed-loop cooling water systems, boilers, and engine coolants.
• Metal Treatment agent for passivating steel and iron surfaces to enhance durability.
• Heat Transfer Fluid Additive to protect piping and heat exchangers in industrial heating and cooling processes.
• Intermediate in Chemical Synthesis for the production of dyes, pharmaceuticals, and other organic compounds.
• Food Preservation (in specific, regulated grades) as a curing agent for meats to prevent bacterial growth.
• Analytical Reagent used in laboratory settings for testing and quantitative analysis.

Quality Control

Our Nitrite is produced and tested under a stringent quality management system to ensure batch-to-batch consistency and reliability. We offer various grades, including industrial and high-purity, with specifications tailored to your application. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its property of being easily oxidized, long-term storage under an inert atmosphere (e.g., nitrogen) is recommended for optimal stability. Maintain storage temperature between 15-25°C.
