Used in biochemical and pharmaceutical research as a dipeptide building block for synthesizing larger peptides and studying protease activity. Commonly employed in enzyme assays to investigate peptidase function, particularly in digestive and metabolic studies. Also utilized in cell culture media formulations to support peptide metabolism research and in the development of peptide-based therapeutics. Its hydrochloride salt form enhances solubility and stability in aqueous solutions, making it suitable for in vitro studies.
