Ammonium acetate is widely used in biochemical research and molecular biology as a buffer solution. It helps maintain a stable pH level during various laboratory procedures, such as DNA and RNA purification. In analytical chemistry, it serves as a mobile phase in high-performance liquid chromatography (HPLC) for the separation and analysis of compounds. Additionally, it is employed in protein crystallization and as a source of ammonia in chemical reactions. In the food industry, it acts as a preservative and acidity regulator. Its versatility also extends to the synthesis of pharmaceuticals and organic compounds.
