This compound is primarily used in peptide synthesis as a building block. It serves as a protected amino acid derivative, where the Boc (tert-butoxycarbonyl) group safeguards the amino functionality during the coupling process. The presence of the 2-methyl group on the phenylalanine side chain introduces steric and electronic effects, which can influence the peptide's structure, stability, and interactions. It is particularly valuable in the development of modified peptides for pharmaceutical research, enabling the creation of analogs with tailored properties for drug discovery, enzyme studies, and biochemical applications. Its use ensures precise control over peptide assembly, making it essential in the synthesis of complex peptide-based therapeutics and biomaterials.
