Request SDS →Ammonium bicarbonate (CAS 1066-33-7, NH4HCO3) is a white crystalline ammonium salt. It is used as a leavening (raising) agent in baked goods, as a blowing agent for foamed plastics and rubber, in ceramics, fire-extinguishing compounds, and boiler-scale removal, and in the manufacture of dyes and pigments.
Frequently Asked Questions
What is the use of ammonium bicarbonate?
Ammonium bicarbonate (CAS 1066-33-7, NH4HCO3) is used as a leavening agent in crackers, cookies, and other baked goods, and as a blowing agent for foamed plastics and rubber. It also serves in ceramics, fire-extinguishing compounds, boiler-scale removal, and dye and pigment manufacture.
Is ammonium bicarbonate the same as baking soda?
No. Baking soda is sodium bicarbonate (NaHCO3); ammonium bicarbonate is NH4HCO3. Ammonium bicarbonate releases ammonia and carbon dioxide on heating and is used where that volatile decomposition is desired, such as flat baked goods.
What is the pH of ammonium bicarbonate?
Aqueous ammonium bicarbonate is mildly alkaline, typically in the weakly basic range. Refer to the SDS and spec sheet for the solution pH at a given concentration.
What grades of ammonium bicarbonate are available?
Ammonium bicarbonate is supplied in food/leavening grade and technical/industrial grade depending on application. Specify your intended use so we provide the correct grade and a conforming Certificate of Analysis.
What UN number and packaging apply to bulk ammonium bicarbonate?
It ships under UN 3077 and classifies under HS 2836.99 (carbonates, other). RawSource supplies it in bulk bags and palletized quantities; request a bulk quote with CoA and SDS for your volume and destination.
