Sodium nitrite is widely used in analytical chemistry as a reagent for diazotization reactions, which are essential in the synthesis of azo compounds. It is also employed in the Griess reagent method for the determination of nitrite levels in various samples, including environmental and biological matrices. Beyond its analytical applications, sodium nitrite serves as a food preservative, particularly in cured meats, where it helps to inhibit bacterial growth and maintain color. Additionally, it is utilized in the production of dyes, pharmaceuticals, and as a corrosion inhibitor in industrial applications.
