Published: 2026-06-15 10:01:43Product Overview
Sodium nitrite is a key inorganic industrial chemical synthesized from soda ash, liquid ammonia and nitric acid. It appears as a white crystalline solid with oxidizing and toxic properties, classified as Class 5.1 dangerous goods for international transport. We supply two mainstream industrial grades — ≥99% Superior Grade and ≥98.5% First Grade — both compliant with China GB/T2367 national standard. Food-grade (≥99%) is also available on request. With excellent anti-rust, antifreeze and bleaching performance, it serves the construction, metallurgy, textile and fine chemical industries worldwide.
