This compound is primarily used in peptide synthesis as a protected amino acid derivative. It serves as a building block for constructing larger peptide chains, particularly in solid-phase peptide synthesis (SPPS) methods. The methyl ester group protects the carboxylic acid functionality, while the hydrochloride salt ensures stability and solubility during reactions. It is commonly employed in research laboratories for developing bioactive peptides, pharmaceuticals, and protein analogs. Its application is crucial in studying peptide structure-activity relationships and designing therapeutic agents targeting various diseases, including cancer, metabolic disorders, and infectious diseases.
