Key Properties
Sodium nitrite (NaNO2) is an inorganic compound that appears as a white to pale yellow crystalline powder. It is primarily used as an analytical reagent due to its high purity level of 98% AR grade, which ensures precise results in various chemical analyses. Sodium nitrite is notable for its role in diazotization reactions and as a nitrite determination reagent in the Griess test. It is also recognized for its applications in food preservation and as a corrosion inhibitor in industrial processes.
Also known as Nitrous acid, sodium salt; Sodium nitrite; Sodium nitrite, AR grade.

- Substance
Sodium nitrite is a white to pale yellow crystalline powder that is hygroscopic in nature, meaning it can absorb moisture from the air. It has a melting point of approximately 271 °C and a boiling point of 320 °C. The density of sodium nitrite is about 2.168 g/cm³. It is soluble in water, with a solubility of approximately 84 g/100 mL at 20 °C, and has a pH value of around 9.0 in a 1% aqueous solution. The compound has a characteristic odor that is often described as faintly sweet or similar to that of nitrous oxide.

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.
