Used in pharmaceutical formulations as a source of aspartate, an amino acid involved in the urea and tricarboxylic acid cycles. It supports metabolic processes and is utilized in some electrolyte and energy-boosting injectable solutions. Also serves as a buffering agent in cell culture media and biopharmaceutical preparations due to its solubility and stability. In research, it acts as a precursor for synthesizing peptides and chiral compounds. Its potassium content makes it useful in studies involving ion transport and nerve function.
