This compound is primarily used in peptide synthesis as a protected amino acid derivative. It serves as a building block for constructing peptides, where the Boc (tert-butoxycarbonyl) group protects the amine functionality during the synthesis process. This allows for selective reactions at other sites of the molecule, ensuring the desired peptide sequence is achieved. It is particularly useful in solid-phase peptide synthesis (SPPS), a method widely employed in the production of peptides for pharmaceutical research, drug development, and biochemical studies. The hydrochloride salt form enhances its stability and solubility, making it easier to handle and incorporate into synthetic workflows. Its application is crucial in the development of therapeutic peptides, vaccines, and other biologically active molecules.
