Key Properties
Sodium nitrite (extra pure) is a widely used reducing/oxidizing salt essential in food preservation, diazotization chemistry, and analytical applications. It is a white to pale yellow crystalline powder that is hygroscopic and highly soluble in water, making it an effective agent in various chemical processes. With a purity of 97%, this grade of sodium nitrite is suitable for both industrial and laboratory use, ensuring high-quality results in applications such as meat curing and dye synthesis. Its molecular weight of 69.00 g/mol and CAS number 7632-00-0 further identify its chemical nature and facilitate its use in regulatory and safety contexts.
Also known as Nitrous acid sodium salt, Sodium nitrous, Sodium nitrite (NaNO2).

- Substance
Sodium nitrite appears as a white to pale yellow crystalline powder. It is hygroscopic, meaning it can absorb moisture from the air. The compound has a melting point of approximately 271 °C (520 °F) and a boiling point of 320 °C (608 °F) when decomposed. It is highly soluble in water, with a solubility of about 84 g/100 mL at 20 °C. The density of sodium nitrite is approximately 2.165 g/cm³. It has a faint, characteristic odor and is stable under normal conditions, although it can decompose when exposed to heat or light.

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.
