Sodium Nitrite (E250)

Description

1. Product Overview
   Sodium Nitrite (E250) is an inorganic salt widely used as a food preservative, corrosion inhibitor, and chemical intermediate. In industrial settings it serves primarily as a curing agent in meat processing, a corrosion-control additive in heat-transfer fluids and boiler water treatment, and a reagent in organic synthesis and dye manufacture. The key value proposition is a high-purity, specification-driven supply that ensures consistent functional performance, regulatory traceability, and safe handling across large-scale manufacturing operations. Strategically, reliable access to certified Sodium Nitrite (E250) mitigates production risk, supports regulatory compliance for food and industrial applications, and optimizes operational continuity for buyers with tight quality and timing requirements.

2. Key Specifications & Technical Characteristics

• Chemical name: Sodium Nitrite (NaNO2), E-number: E250.

• Chemical composition: Sodium nitrite as primary component; impurity limits (typical): sodium chloride, sodium nitrate, moisture, heavy metals — controlled to industry norms.

• Purity/grade: Food-grade / technical-grade options available; typical assay ≥ 99.0% (food-grade variant available to customer specification).

• Physical form: Fine crystalline powder or granular solid.

• Color: White to slightly off-white.

• Particle size: Distributed to customer requirement; typical D90 ≤ 500 µm for granular; tailored milling available for powdered grades.

• Bulk density: Typical 700–900 kg/m3 (depends on packing and particle size).

• Solubility: Highly soluble in water; rapid dissolution profile for process integration.

• pH (aqueous solution): Slightly alkaline in solution (depends on concentration).

• Moisture content: Controlled, typical ≤ 0.5% w/w (food-grade tighter on request).

• Heavy metals: Controlled to meet regulatory limits; certificates provided.

• Packaging options: 25 kg multi-wall paper bags with inner polyethylene liner, 500 kg FIBCs (big bags), 1 MT bulk bags, and ISO tank or bulk tanker options for large volume buyers.

• Shelf life and storage: Recommended 24 months when stored in cool, dry, well-ventilated conditions away from reducing agents and combustibles; shelf life may vary by grade and packaging — subject to certificate.

• Regulatory & compliance documentation: Certificate of Analysis (CoA), Safety Data Sheet (SDS), and regulatory declarations (food-grade documentation available on request).

3. Core Industrial Applications

• Food processing (meat curing): Used as a curing and color-fixing agent in processed meat production; provides microbial inhibition (notably Clostridium botulinum control when used per regulatory guidance). Delivers consistent curing kinetics and predictable color development versus variable or lower-grade substitutes.

• Water and boiler treatment: Functions as an oxygen scavenger/corrosion inhibitor in closed-loop heat-transfer and boiler systems; maintains metal integrity and reduces downtime and maintenance costs compared with untreated systems.

• Chemical intermediates & organic synthesis: Employed in diazotization reactions and as an oxidizing/nitrosating agent in dye, pharmaceutical, and specialty chemical manufacture; offers high reactivity and batch-to-batch consistency that supports predictable yields and process control.

• Metal finishing & corrosion control: Used in pickling and passivation chemistries to inhibit corrosion during storage and transport of metal parts.

• Analytical and laboratory uses: Standard reagent in industrial QC laboratories for calibration and specific analytical methods.
  Why it outperforms alternatives:

• Consistent assay and low impurity profile reduce process variability.

• Controlled particle size and solubility support faster dissolution and uniform dosing.

• Food-grade traceability and documentation simplify regulatory compliance for producers.

4. Competitive Advantages

• Quality consistency: Manufactured to strict quality systems with batch CoAs, in-line testing, and traceability from raw material sourcing to final dispatch.

• Supply reliability: Multiple production sources and inventory-managed distribution network to reduce lead-time volatility; strategic safety stocks for bulk buyers.

• Logistics capability: Flexible packaging and containerized load planning (20 MT bulk per 20’ container as standard bulk loading), coordinated export documentation, and freight-forwarder partnerships to support international shipments.

• Price competitiveness: Economies of scale for bulk contracts, transparent pricing models tied to volume and contract term, and competitive freight routing to optimize landed cost.

• Sustainability & environmental considerations: Options for lower-impact packaging, waste management protocols at manufacturing sites, and supplier compliance with local environmental regulations; end-user guidance to minimize nitrite discharge in effluents.

• Technical support & documentation: Dedicated technical service for specification alignment, CoA and SDS provision, regulatory support for food-grade use, and on-request formulation guidance to optimize dose and performance.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): BULK 20 MT.

• Typical bulk loading capacity: 20 MT per 20’ container (bulk bag/FIBC or parcelized 25 kg bags; loading density depends on packing configuration).

• Lead times: Subject to order size and stock positions; typical lead time for bulk replenishment 2–6 weeks — expedited options available for established contracts.

• Payment & contract terms: Available on request and negotiable by volume, term, and destination (trade terms: FOB/CFR/CIF/EXW as agreed).

• Quality assurance: Each shipment accompanied by CoA, SDS, and transport documentation; third-party testing available on request.
