Sodium nitrite is primarily used as a curing agent in food preservation, particularly in the meat industry, where it helps to inhibit the growth of harmful bacteria and enhances the color and flavor of cured meats. Additionally, it serves as a diazotization reagent in the synthesis of azo dyes, which are widely used in textiles and other industries. In analytical chemistry, sodium nitrite is utilized in various reactions, including the determination of nitrite levels in water and food samples. Its role as an oxidizing agent also finds applications in organic synthesis and as a corrosion inhibitor in industrial processes.
