Ammonium bicarbonate
Chemical Name: Ammonium bicarbonate
CAS No.: 1066-33-7
Appearance: White Solid
Molecular Formula: CH5NO3
Molecular weight: 79.06
Sample: Available
Industrial-grade ammonium bicarbonate has a purity of at least 99%, appearing as white crystalline powder with a slight ammonia smell. It decomposes at 105°C and has a boiling point of about 169.8°C. Its vapor pressure is negligible at 25°C, and relative density is 1.58 at 20°C. It dissolves in water at 220g/L (20°C), but is insoluble in ethanol, acetone, and chloroform. This compound is thermally unstable and decomposes when heated; it is not compatible with strong acids or strong bases.

Product Application of Ammonium bicarbonateCAS#1066-33-7
Ammonium bicarbonate (1066-33-7) is widely used as a nitrogen fertilizer suitable for many soil types. It supplies both ammonium nitrogen and carbon dioxide required for plant growth. However, it has a relatively low nitrogen content and tends to form lumps easily.
