Frequently Asked Questions
What is the CAS number and formula of sodium nitrate?
Sodium nitrate has CAS number 7631-99-4 and the chemical formula NaNO3. It is also known as Chile saltpetre, nitrate of soda, or soda niter.
What is the HSN code for sodium nitrate?
Sodium nitrate is classified under HSN code 2834 21 00. This is stated on our technical data sheet (document SPC-TDS-PWD-020).
Is sodium nitrate an oxidiser?
Yes. Sodium nitrate is a Class 5.1 oxidiser, UN 1498 — it intensifies fire, so keep it away from combustible materials, heat, and reducing agents. Store it cool, dry, and well-ventilated in sealed bags, and avoid dust inhalation.
What is the difference between sodium nitrate and sodium nitrite?
They are different chemicals: sodium nitrate is NaNO3 (CAS 7631-99-4), while sodium nitrite is NaNO2 (CAS 7632-00-0). Our technical-grade sodium nitrate limits sodium nitrite content to 0.01% mass max. We stock both products.
What specification does technical-grade sodium nitrate meet?
Our sodium nitrate meets IS 5058 (technical grade): 99.0% mass minimum assay as NaNO3, white crystalline solid, moisture 0.6% max, chloride (as NaCl) 0.20% max, iron 30 ppm max, and pH 6.5–9.0 in 5% solution. A branded TDS and MSDS are available on request.
