VWR Sodium Nitrite (NaNO₂) is a high-purity, white crystalline salt used widely in analytical chemistry, synthesis, corrosion inhibition, and diazotization reactions. With an assay of ≥99.0% (on dried substance) and compliance with both European Pharmacopoeia (Ph. Eur.) and ACS standards, this AnalaR NORMAPUR® analytical reagent offers exceptional quality for regulated laboratory applications.
Sodium nitrite functions both as an oxidizing agent and reducing intermediate, and is known for its high reactivity. It is classified as oxidizing, toxic, and environmentally hazardous, and requires safe handling under controlled laboratory conditions.
