Application
Ammonium bicarbonate serves multiple purposes across various industries due to its versatile properties. As a leavening agent and dough strengthener, it plays a key role in baking and food processing, where it helps achieve the desired texture and volume in baked goods. In the field of healthcare, it's used in cough syrups and as an antacid, providing therapeutic benefits. Its buffering capability and volatile nature make it valuable in chemical laboratories, particularly for lyophilization and protein digestion processes such as trypsin digestion and MALDI mass spectrometry. In agriculture, it functions as a low-nitrogen fertilizer, primarily used in China. Moreover, its application extends to industrial processes, where it's integral to the production of dyes, pharmaceuticals, catalysts, ceramics, fire-retardants, and plastics. Its ability to decompose under heat, releasing ammonia and carbon dioxide, further exemplifies its utility in various scientific and industrial applications.
