Product Description

High-Purity Sodium Nitrite for Catalyst Manufacturing & Industrial Applications

Sodium Nitrite (NaNO₂) is a versatile chemical essential for industries ranging from catalyst manufacturing to pharmaceuticals. With a CAS number 7632-00-0 and molecular weight of 69.00, our high-purity product is engineered to meet stringent quality standards. As white to slightly yellow crystals, it excels in applications requiring precise impurity control (Fe ≤30ppm) and customizable morphology. Whether you’re developing advanced catalysts or optimizing metal treatment processes, our solutions combine technical excellence with environmental responsibility.

Key Applications of Sodium Nitrite

1. Catalyst Production

Used as a nitriding agent in hydrogenation and methanol synthesis catalysts, our low-iron product prevents catalyst deactivation.

2. Metal Surface Treatment

Enhance corrosion resistance in steel and cast iron with pH-adjusted Sodium Nitrite passivation solutions.

3. Pharmaceutical Intermediates

Enable precise diazotization reactions with consistent purity grades.

4. Renewable Energy Systems

Integrate into molten salt mixtures for solar thermal storage.
