Used in biochemical and analytical laboratories to maintain a stable pH environment, particularly in processes like chromatography, electrophoresis, and enzyme reactions where pH control is critical. Commonly applied in DNA and protein purification, as it helps prevent denaturation and supports optimal activity of biological molecules. Also utilized in pharmaceutical formulations to ensure product stability and in environmental testing for sample preservation. Its buffering capacity in the slightly acidic to neutral range makes it ideal for microbiological media preparation and fermentation monitoring.
