Used in peptide synthesis as a protected amino acid derivative, it helps in the controlled construction of peptide chains, particularly in pharmaceutical research. Its Boc (tert-butoxycarbonyl) group provides stability during synthesis, while the methoxy group can influence the peptide's biological activity. Commonly applied in the development of drugs targeting neurological disorders, cancer, and metabolic diseases due to its ability to mimic natural amino acids and modulate peptide interactions.
