Sodium Nitrite

Chemical Formula: NaNO₂
Sodium Nitrite is a white to slightly yellow crystalline powder with strong oxidizing and preservative properties. Soluble in water and hygroscopic by nature, this compound plays a critical role in the food industry, pharmaceuticals, and chemical manufacturing as a corrosion inhibitor, antimicrobial agent, and precursor to diazo compounds.
Appearance:
White to pale yellow crystalline powder
Uses:
Food & Beverage Industry:
Widely used as a preservative and color fixative in cured meats and poultry. Helps inhibit the growth of Clostridium botulinum and enhances the characteristic pink color of processed meats.
Pharmaceutical Applications:
Used in cyanide poisoning antidote kits and in the synthesis of antihypertensive drugs and vasodilators.
Industrial Applications:
Acts as a corrosion inhibitor in closed-loop cooling systems and antifreeze solutions. Also used in metal surface treatment, pickling, and electroplating processes.
Chemical Manufacturing:
Key intermediate in the production of azo dyes, rubber chemicals, and diazotization reactions. Plays a role in organic and inorganic synthesis as a nitrosating and oxidizing agent.
Laboratory Use:
Utilized in analytical chemistry for nitrosation reactions, titrations, and sample preservation.
