Ammonium hydrogen carbonate ((NH4)HCO3)-Crystalline introduce:
Ammonium bicarbonate is an inorganic compound with formula (NH4)HCO3, simplified to NH5CO3. The compound has many names, reflecting its long history. Chemically speaking, it is the bicarbonate salt of the ammonium ion. It is a colourless solid that degrades readily to carbon dioxide, water and ammonia.

Ammonium bicarbonate is a commonly used reagent for industrial and research procedures. It acts a good buffer in lyophilization and matrix assisted laser desorption. It is also utilized for the in-gel digestion of proteins by trypsin and in the MALDI mass spectrometric analysis of proteins. It is also used to make other ammonium compounds, in food processing, and for other uses. Ammonium bicarbonate can be used to study biological buffers. It is also used in a study that demonstrated that ammonium bicarbonate salts, which can be regenerated using low-temperature waste heat, can also produce sufficient voltage for hydrogen gas generation in a microbial reverse-electrodialysis electrolysis cells. It has also been used in a study that developed a fast and sensitive method for the simultaneous determination of Sudan dyes in food samples using partial filling micellar electrokinectic chromatography-mass spectrometry.
