Frequently Asked Questions
What is the CAS number and HSN code for sodium bicarbonate?
Sodium bicarbonate carries CAS 144-55-8 and HSN code 2836 30 00. The chemical formula is NaHCO3, and the same compound is also listed as sodium hydrogen carbonate.
Is sodium bicarbonate the same as baking soda?
Yes. Baking soda, bicarbonate of soda, and sodium hydrogen carbonate are all the same compound, NaHCO3 (CAS 144-55-8). We supply technical grade to IS 2079 for industrial buyers — not the retail food product.
What is the specification of technical grade sodium bicarbonate?
Our material is technical grade per IS 2079: NaHCO3 assay 99.0% mass min, sodium carbonate 0.5% mass max, moisture 0.20% mass max, iron 20 ppm max, and pH of a 1% solution between 8.0 and 8.6. It is a white crystalline powder, with the assay range aligned with BP/USP for purity.
What is sodium bicarbonate used for?
Industrially, sodium bicarbonate works as a mild alkali for acid neutralisation and pH buffering, and goes into cleaning formulations, fire-extinguisher dry powders, water treatment, and flue-gas scrubbing. We supply the technical grade (IS 2079) suited to these industrial applications.
Who manufactures the sodium bicarbonate that SPC distributes?
We distribute sodium bicarbonate manufactured by Gujarat Alkalies and Chemicals Limited (GACL) of Vadodara, Gujarat — a large-scale chlor-alkali manufacturer, ISO 9001 certified. TDS and MSDS documents are available for this product.
Can I buy sodium bicarbonate in bulk from a supplier in Chennai?
Yes. We stock sodium bicarbonate in 25 kg HDPE/paper laminated bags at our Redhills warehouse in Chennai and dispatch across South India. Order sizes depend on packaging and current stock — call or WhatsApp +91 86087 80096 for a quote.
