Sodium Azide is a high-purity, pharmacopeial-grade inorganic compound used in pharmaceutical and analytical laboratories for microbiological preservation, reagent preparation, and certain chemical syntheses.
🏭⚗️ Production
Prepared under strictly controlled conditions to ensure high purity, low moisture content, and absence of metallic contaminants. Supplied in chemically resistant, tightly sealed containers to prevent exposure to moisture, air, and incompatible materials. Quality is verified according to pharmacopeial and analytical standards.
🔬 Properties
A white, crystalline solid with high solubility in water. Highly reactive and toxic; decomposes under heat, shock, or friction to release toxic gases. Chemically stable under proper storage conditions in a cool, dry, tightly closed container away from metals and acids.
🧪 Applications
Used in pharmaceutical and analytical laboratories as a preservative in biochemical solutions, in certain reagent preparations, and in specialized chemical syntheses. Suitable for experimental protocols requiring microbial inhibition or controlled chemical reactivity.
⚠️ Safety
Extremely toxic and potentially explosive; can cause severe poisoning, skin, and eye irritation. Handle with gloves, goggles, and protective clothing in a well-ventilated area or fume hood. Avoid heat, shock, friction, and contact with heavy metals, acids, or other incompatible substances. Store in a cool, dry, tightly sealed container. Dispose of according to strict laboratory and environmental safety regulations.
