This compound is primarily used in peptide synthesis as a protected amino acid derivative. It serves as a building block for creating custom peptides in research and pharmaceutical development. The Boc (tert-butyloxycarbonyl) group protects the amino group during the synthesis process, ensuring selective reactions at other sites. The presence of the 3-methyl group on the phenylalanine side chain allows for the study of steric and electronic effects in peptide structures. As a D-enantiomer, it enables the exploration of stereochemical influences on peptide conformation and activity. It is particularly useful in designing peptides with specific biological activities or improved stability, making it valuable in drug discovery and biochemical studies.
