Used as a buffering agent in pharmaceutical formulations to maintain stable pH levels. Employed in electroplating baths to improve metal deposition efficiency and surface finish. Serves as a precursor in organic synthesis, particularly in malonic ester synthesis variants, for the preparation of specialty chemicals, active pharmaceutical ingredients, and other carboxylic acid derivatives. Applied in analytical chemistry as a component in buffer solutions for electrophoresis and chromatography. Also utilized in cosmetic products for pH adjustment and stabilization.
