Ammonium acetate solution is widely used in biochemical research and molecular biology as a buffer in various applications, including protein purification and DNA/RNA precipitation. It is particularly effective in maintaining stable pH levels during enzymatic reactions and chromatography processes. In analytical chemistry, it serves as a mobile phase component in liquid chromatography-mass spectrometry (LC-MS) for the analysis of polar compounds due to its volatility and compatibility with mass spectrometry detectors. Additionally, it is employed in the synthesis of pharmaceuticals and organic compounds as a source of ammonia and acetate ions. Its versatility also extends to industrial applications, such as in the production of textiles and plastics, where it acts as a catalyst or stabilizer.
