Sodium nitrite, with the formula NaNO₂, is a white to pale yellow crystalline solid. It has a molar mass of 69.00 g/mol and a melting point of 271 °C (520 °F), at which it decomposes. Sodium nitrite is highly soluble in water and slightly soluble in alcohol. It is hygroscopic, meaning it readily absorbs moisture from the air.
Applications:
- Food Industry:
Sodium nitrite is primarily used as a preservative and curing agent in processed meats . Its use is carefully regulated due to the potential formation of nitrosamines, compounds with carcinogenic risks when consumed in excess.
- Chemical Industry:
Sodium nitrite serves as an intermediate in dye and pigment production. It is used in organic synthesis, particularly in diazotization reactions, which are essential for producing azo dyes and other compounds.
- Industrial Uses:
Sodium nitrite acts as a corrosion inhibitor in closed-loop cooling systems and a heat transfer agent in certain industrial applications. Its oxidizing properties make it useful in metal treatment processes and thermal energy storage systems.
Packing:
Available in 25 kg bags, 50 kg bags, or bulk packaging options to suit industrial and commercial requirements.
