Product: Sodium Nitrite (NaNO₂)

CAS No.: 7632-00-0
Hazard Class: 6.1 (Toxic) + 5.1 (Oxidizer)
UN No.: 1500
Appearance: White to yellowish crystalline powder

Description: Sodium nitrite is produced through absorption of nitrogen oxides in sodium hydroxide solution or by reduction of sodium nitrate, serving as a critical but highly regulated chemical for meat curing (inhibits botulism at 50-200ppm), industrial corrosion inhibition (closed-loop systems), and diazotization reactions in dye/pharmaceutical manufacturing. Its dual toxicity (oral LD50 85mg/kg) and oxidizing properties require strict handling controls.
