Sodium Nitrite, Extra Pure

Sodium Nitrite (NaNO₂) extra pure grade is a general inorganic chemical used widely in analytical chemistry, microbiology, the manufacture of pharmaceuticals, and food technology. As a reducing agent, preservative, and corrosion inhibitor, the chemical occurs as white or yellowish crystalline powder with high water solubility and stability under normal laboratory conditions.

In biochemistry and microbiology, Sodium Nitrite is used on a daily basis in nitrate tests for reduction to determine the presence of nitrate-reducing bacteria, specifically detecting members of the family Enterobacteriaceae. The reagent is of particular significance in anaerobic respiration research and is used in the identification of the build-up of nitrite in bacterial cultures. Used in diazonium salt synthesis in organic chemistry and as a coupling agent in the synthesis of pigments and dyes.

Sodium Nitrite is a very potent food processing antioxidant and antimicrobial food additive that is equivalent to curing meat products. It serves as an inhibitor of the growth of Clostridium botulinum, the major cause of botulism, thereby ensuring food safety. It is used industrially as a corrosion inhibitor in closed-loop water systems, where it prevents oxidation and rust development on metal surfaces.

The other pure grade offers assay value of high purity with minimal contamination, and it is particularly suitable for sensitive lab procedures and analytical testing. It is also used in the pharmaceutical sector for active compound synthesis and also in the production of rubber chemicals and corrosion-inhibition formulations.

Sodium Nitrite has to be handled with care, as it is toxic in its pure state and must be stored in secure conditions in closed containers away from incompatible materials like acids and organic materials. Its stability and reactivity guarantee that it is an essential component in a vast majority of applications, from chemical research and diagnostics to water treatment and synthetic chemistry.
