Sodium nitrite is NaNO2 (CAS 7632-00-0). This is the product and RFQ hub for industrial supply. Because sodium nitrite is an oxidizer and may be regulated by use and destination, the commercial order must identify the customer, permitted industrial duty, specification, packing, transport documents and receiving controls.
This page does not grant approval for food, pharmaceutical, medical or other regulated uses. Those duties require the buyer's named standard, legal review and current supporting evidence. We do not publish emergency instructions, a public stock claim or an invented universal price.
Specification and COA fields
| Field | Procurement purpose |
|---|---|
| Identity | NaNO2 and CAS 7632-00-0 on the PO, label and COA |
| Assay | Minimum content and agreed analytical method |
| Impurities | Nitrate, chloride, sulfate, insolubles and moisture where required |
| Physical condition | Appearance, caking, particle form and receiving acceptance |
| Documents | Recent lot COA, current SDS, labels and transport documentation |
Do not accept "industrial grade" as the entire specification. The order should distinguish guaranteed limits from typical values and should state what happens if receiving inspection finds damaged packing, an unmatched lot number or an out-of-limit result.
Industrial application boundaries
Sodium nitrite can be used in permitted chemical-intermediate, metal-treatment and corrosion-control processes. Application suitability depends on the buyer's formulation, legal status and process validation. The supplier can provide product identity and lot documents; the plant owner remains responsible for use approval and operating conditions.
We do not provide curing recipes, medical dosing or instructions that could bypass regulated controls. If the intended use is not clearly industrial and lawful, it must be reviewed before sale.
Safety, segregation and receiving
Sodium nitrite is identified as an oxidizer by public safety references. Storage and transport must follow the current SDS and applicable law, with segregation from incompatible materials and protection against contamination. The receiving team should verify bag integrity, label, lot number, quantity and documents before release.
For a first order, agree the sample or recent-lot COA review, packing configuration, pallet treatment, container plan and responsible contact for discrepancies. Product webpages do not replace an SDS or site-specific risk assessment.
Do not confuse sodium nitrite with
- Sodium nitrate, NaNO3, which is a different salt.
- Sodium sulfite or sodium metabisulfite, which have different chemistry and procurement uses.
- A food-curing label or pharmaceutical specification, which cannot be inferred from industrial supply.

FAQ
What is the CAS number? 7632-00-0.
Is industrial sodium nitrite automatically food grade? No. Regulated uses require the applicable standard and current evidence.
What documents should accompany a shipment? The agreed recent lot COA, current SDS, labels and transport documents.
Technical references
Identity and synonyms: PubChem sodium nitrite. Safety classification must be checked against the current SDS; NIOSH materials identify sodium nitrite as an oxidizer.
