Overview
Sodium Nitrate (CAS 7631-99-4) is one of the salts & minerals products Suraj Chemicals supplies to industrial, institutional and manufacturing buyers across India from our Chennai base. It is commonly used for oxidizer in industrial and specialty glass manufacturing; corrosion inhibitor in closed-loop systems; fertilizer raw material, among other applications in the salts & minerals category. We pack Sodium Nitrate in 25/50 kg bags; bulk supply on request, and can arrange bulk, drum or tanker quantities for larger requirements — full characteristics, applications and downloadable documentation are below, or you can request a quote directly.

Safety & Handling Summary
| Topic | Summary |
|---|---|
| Signal word | Warning |
| GHS hazards | H272 — May intensify fire; oxidizer |
| Incompatible with | Incompatible with, Reason/Effect |
| Gloves | Chemical-resistant gloves (nitrile or PVC) |
| Eye / face | Safety glasses with side shields or chemical splash goggles |
| Respiratory | Not normally required under good ventilation. If dust levels exceed exposure limits, use a filtering half-mask respirator (type P1/P2) |
| Body | Standard work clothing; avoid clothing contamination given oxidiser hazard (dry, contaminated organic material with residual nitrate can become fire-prone) |
| Transport (road) | UN1498 · Class 5.1 · Packing group III |
| Emergency handling | First aid, fire-fighting and spill / release measures are in Sections 4–6 of the SDS. Emergency contact: +91 70927 22822 / +91 98402 84032. |

Buyer’s Notes
Choosing the grade. This lot reads 99.61% purity against a 99.00% minimum. Technical grade is fine for glass, salts and corrosion inhibition; fertiliser users look at moisture and flow.
What to check on the spec sheet. Purity on dry basis, loss on drying, chloride, nitrite, alkalinity and iron. Low nitrite and iron matter in glass work.
Handling and storage. Strong oxidiser. Keep it dry, apart from combustibles, organic matter, acids and reducing agents, and avoid contamination of the stock.
Where it is used. Glass manufacture, closed-loop corrosion inhibition, fertiliser raw material and heat-transfer salts.
Frequently Asked Questions
What is Sodium Nitrate?
Sodium Nitrate is supplied by Suraj Chemicals as white crystalline powder / prills, identified by CAS number 7631-99-4. It falls under our Salts & Minerals range — see the Specification Sheet table above for its full characteristics.
What is Sodium Nitrate used for?
Typical applications include: Oxidizer in industrial and specialty glass manufacturing; Corrosion inhibitor in closed-loop systems; Fertilizer raw material; Heat-transfer salt formulations.
How should Sodium Nitrate be stored and handled?
Store in a dry, covered area away from combustible material — strong oxidizer.
What packaging and pack sizes does Suraj Chemicals supply Sodium Nitrate in?
25/50 kg bags; bulk supply on request. Contact us if you need a different pack size, or a bulk/tanker quantity.
What is the shelf life of Sodium Nitrate?
Typically 3–6 months from date of manufacture when stored sealed, in a cool place away from direct sunlight and heat. Active content in hypochlorite / oxidising products declines gradually over time, so this is one to watch closely. As with any industrial chemical, request the current batch's manufacturing date and a fresh certificate of analysis for orders where exact remaining shelf life matters.
Is Sodium Nitrate hazardous to handle?
Yes. Sodium Nitrate is classified under GHS (signal word: Warning) as: may intensify fire; oxidizer (H272). Follow the storage and handling guidance above, use appropriate PPE, and download the Safety Data Sheet (SDS/MSDS) in the sidebar above for full GHS hazard, handling and PPE details.
Is a Specification Sheet, TDS or MSDS available for Sodium Nitrate?
Yes. a downloadable Specification Sheet (PDF) with full characteristics and specifications is available above, and a downloadable Safety Data Sheet (SDS/MSDS) for Sodium Nitrate is also available above.
Can I get a sample or discuss order quantity for Sodium Nitrate?
Yes. use the Request Price & Availability button or WhatsApp us with your required quantity, and our team will confirm pricing, minimum order quantity, sample availability and delivery timelines for Sodium Nitrate.
