Used in peptide synthesis as a protected amino acid derivative, it helps in the controlled formation of peptide bonds. It is particularly valuable in solid-phase peptide synthesis (SPPS) for creating specific peptide sequences. The hydrochloride salt form enhances its stability and solubility in various solvents, making it easier to handle during reactions. It is also employed in the development of pharmaceuticals, especially in the production of peptide-based drugs, where precise amino acid incorporation is critical. Additionally, it finds use in biochemical research for studying protein structures and functions.
