Selection Guide: Industrial vs. Food Grade
Selecting the appropriate grade is critical for regulatory compliance and end-product safety.
1. Technical Grade
The standard for Metal Treatment, Dye Synthesis, and Concrete Admixtures. It is optimized for industrial-scale use where cost-efficiency and high active matter are the primary drivers.
2. Food Grade (E250 / FCC)
Specifically refined for the Meat Processing Industry. This grade undergoes rigorous testing for heavy metals (Lead, Arsenic, Mercury) and impurities to meet global food safety standards.
Sodium Nitrite for Sale
Sodium Nitrite (NaNO2) is a critical inorganic salt used across diverse industries, ranging from metal surface treatment and chemical synthesis to food preservation. As an integrated manufacturer and exporter, HOO CHEMTEC provides premium Sodium Nitrite in both Technical and Food Grades, engineered for high stability and reliable performance in global B2B supply chains.
Core Features & Technical Advantages
HOO CHEMTEC’s Sodium Nitrite is synthesized with strict control over moisture and impurity levels to prevent caking and ensure rapid solubility.
- Potent Corrosion Inhibition: In the metal industry, it acts as an effective anodic inhibitor, forming a protective oxide layer on steel and iron to prevent rust during processing and storage.
- Versatile Chemical Intermediate: A fundamental building block for the production of diazo dyes, pigments, and various organic compounds used in the pharmaceutical and rubber industries.
- High-Performance Heat Transfer: When blended with other salts, it creates high-efficiency heat transfer media for solar energy storage and industrial chemical reactors.
- Superior Antimicrobial Action (Food Grade): Effectively inhibits the growth of Clostridium botulinum in cured meats while stabilizing the characteristic pink color and flavor profile.
- Controlled Particle Size: Available in various crystalline sizes to suit different industrial mixing requirements, from fine powders to larger crystals.
What is Sodium Nitrite Used for
For the Food Industry: It is primarily used as a color-fixing agent and preservative in cured meat products (e.g., ham, sausage) to develop a pink color and inhibit the growth of bacteria, including Clostridium botulinum.
In Chemical & Industrial Processes: Sodium Nitrite serves as a key intermediate in the production of dyes, pharmaceuticals, and rubber. It also functions as a corrosion inhibitor in metal treatment, a bleaching agent for textiles and paper, and a component in certain explosive formulations.
In Medical & Analytical Applications: It is used as an antidote for cyanide poisoning and as a vasodilator in treating certain cardiovascular conditions. Additionally, it serves as a reagent in analytical chemistry.
FAQ of Sodium Nitrite
Yes, Sodium Nitrite is classified as an oxidizer and is toxic if swallowed. It must be handled with appropriate PPE and stored away from acids and flammable materials. Hoochemtec provides full GHS-compliant SDS for all shipments.
While related, they have different chemical properties. Sodium Nitrite (NaNO2) is a more potent reducing agent and is specifically used for diazotization and meat curing, whereas Sodium Nitrate (NaNO3) is primarily used as a fertilizer and in glass production.
It should be stored in a cool, dry, well-ventilated warehouse. Because it is slightly hygroscopic, Hoochemtec uses moisture-proof PE liners to ensure the product remains free-flowing.
It is available in standard 25kg bags and in bulk quantities of 25 metric tons (25MTS).
Store in a cool, dry, well-ventilated, and dedicated area. Keep the container tightly sealed and away from moisture, heat, sparks, and incompatible materials (especially reducing agents and combustibles). Strictly adhere to all relevant safety regulations.
