CAS No.: 1066-33-7
Molecular Formula: NH?HCO?
Molecular Weight: 79.06 g/mol
1. Product Description
Ammonium Bicarbonate is a white crystalline powder or granule with a strong ammonia odor. It is moderately soluble in water and decomposes easily upon heating, releasing carbon dioxide and ammonia. It is commonly used as a leavening agent, blowing agent, pH regulator, and nitrogen source in food, agriculture, and industrial applications.
