CAS 7632-00-0 — Sodium nitrite

Sodium nitrite (NaNO2, CAS 7632-00-0) is a versatile inorganic compound primarily used as a preservative in cured meats to prevent bacterial growth, as a corrosion inhibitor in industrial processes, and in laboratory settings for analytical chemistry. It is also employed in metallurgy for heat treatment of metals and as a reagent in organic synthesis. This white to yellowish crystalline powder has a molecular weight of 69.00 g/mol and is stored at ambient temperatures. It carries a **Danger** signal word due to its toxicity and environmental hazards. Molekula supplies sodium nitrite from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
