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
