Sodium Nitrite

Product Overview

Sodium Nitrite, universally recognized by its CAS registry number 7632-00-0, stands as a pivotal inorganic compound within the global chemical supply chain. While often confused with Sodium Nitrate due to nomenclature similarities, this substance possesses a distinct chemical identity defined by the molecular formula NaNO2 and a molecular weight of 68.99. Physically, it manifests as white or light yellow crystals and granules that exhibit deliquescent properties, meaning it readily absorbs moisture from the air. It is highly soluble in water, though only slightly soluble in alcohols and ethers. Our production facilities utilize advanced synthesis routes to deliver industrial purity levels that meet the rigorous demands of downstream formulations.

Technical Specifications

Quality consistency is the cornerstone of our manufacturing philosophy. We provide Sodium Nitrite in multiple grades, including Reagent Grade A.R., Chemical Pure (C.P.), and USP31 standards, catering to diverse industrial and regulated needs. The table below details the critical specification limits that define our product quality:

Industrial Applications

The functional versatility of Sodium Nitrite enables its use across several key sectors. In the textile industry, it acts as a crucial dye mordant and a bleaching agent for delicate natural fibers like silk and flax, ensuring colorfastness and brightness. In metallurgy and metalworking, it serves as an effective corrosion inhibitor for raw steel materials, preventing oxidation during storage and transit. It is also utilized as a thermal-treatment agent in metal processing. Furthermore, its role as a diazotizing salt is fundamental in the synthesis of organic compounds and azo dyes. This broad application profile makes it a reliable choice for manufacturers seeking a multi-functional chemical raw material.

Safety and Storage Guidelines

Safe handling and storage are paramount when dealing with oxidizing agents like Sodium Nitrite. Products must be stored in a cool, draughty warehouse environment, strictly kept away from fire sources and excessive heat. The warehouse temperature should not exceed 30℃, with relative humidity maintained at a maximum of 80%. Segregation is critical; this material must be stored separately from reducing agents, reactive metal powders, acids, and combustible substances to prevent potential hazardous reactions. Storage areas should be equipped with appropriate spill containment materials to manage any accidental releases effectively.

Packaging and Quality Assurance

We understand the importance of product integrity during logistics. Our standard packaging consists of 25kg woven bags lined with double-layer plastic bags to protect against moisture and contamination. Every shipment is accompanied by comprehensive documentation, including a Certificate of Analysis (COA), ensuring transparency and compliance. As a global manufacturer, we prioritize consistent bulk pricing and reliable supply chains to support your production schedules.
