Description

Sodium Azide is a versatile inorganic chemical compound widely recognized for its role as a preservative in diagnostic and biological applications. Its primary commercial value lies in its potent biocidal properties and its function as a precursor in the synthesis of other valuable chemicals, including lead azide for explosives and various organic azides. This product is essential for manufacturers and research institutions in the pharmaceutical, biotechnology, automotive safety (airbag), and chemical synthesis sectors. We supply high-purity Sodium Azide CAS NO 26628-22-8 to meet the stringent demands of these global industries.

Application

• Diagnostic Reagent Preservative: Used as a bacteriostatic agent in clinical laboratory reagents, buffers, and antibody solutions to prevent microbial growth.
• Automotive Safety Systems: Serves as a key propellant precursor in the gas generators for vehicle airbag inflators.
• Chemical Synthesis: A fundamental starting material for the preparation of other azide compounds, including organic azides used in "click chemistry" and pharmaceutical intermediates.
• Agriculture & Pest Control: Employed in the formulation of certain pesticides and soil fumigants.
• Laboratory Research: Utilized in biochemical studies, for example, as an inhibitor of cytochrome c oxidase in mitochondrial respiration research.
• Wastewater Treatment: Acts in some contexts as a nitrification inhibitor in biological treatment processes.

Quality Control

Our Sodium Azide is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and impurity profiles. We provide Certificates of Analysis (COA) with every shipment, detailing key parameters such as assay, heavy metal content, and clarity of solution. Our quality commitment supports compliance with relevant global standards for industrial and laboratory use.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flames. Due to its hygroscopic (moisture-sensitive) and strong oxidizing nature, it must be kept separate from acids, reducing agents, and combustible materials. Recommended storage temperature is 15-25°C.
