Sodium nitrite is a chemical compound with various industrial and culinary applications. In the food industry, it is commonly used as a preservative and color fixative, particularly in processed meats like bacon, hot dogs, and ham, to inhibit bacterial growth and maintain product color. Beyond its role in food preservation, sodium nitrite is utilized in chemical processes, such as the production of dyes and pharmaceuticals, as well as in some cooling and heating systems to prevent corrosion. However, its use in food has raised concerns due to potential health risks associated with the formation of nitrosamines, which are known carcinogens, when exposed to certain conditions. Consequently, regulatory limits and guidelines exist to ensure its safe use in food products.

Sodium nitrite is commonly used as a reagent catalyst and nitrating agent in organic synthesis and also a cocatalyst in the catalytic oxidation of alcohols It is used as a color fixative in dyeing and printing textiles and as an intermediate in metal treatment and finishing It is also employed in bleaching photography rubber accelerators detinning solutions greases and medicines Sodium Nitrite Granular WC Code No 1903702 Sales Specifications Appearance White or Slightly White or Slightly Yellowish Crystalline Powder Purity on dry basis 9900 Min Los on drying 050 Max Alkalinity as Na2Co3 020 Max Chloride as Cl 005 Max Sodium Nitrate 100 Max Water Insoluble 005 Max Iron as Fe 0002 Max Heavy metal as Pb 50 ppm Max Clarity of 40 Aqueous Solution Clear solution after 15 min Anticaking Agent 020 Max BSS Sieve NaNO2 25 004 to 10 36 18 to 7 60 32 to 48 85 18 to 45 100 25 to 125 3 150 15 to 40 200 08 to 25 240 04 to 08 300 03 to 06 400 015 to 06 400 01 to 03 Packing 5512 Lb bag 40 bags per pallet DOT Transportation UN No 1500 Proper shipping name Sodium nitrite Hazard Class 51 61 Packing Group III
