This compound is widely used in peptide synthesis as a building block. It serves as a protected form of beta-homophenylalanine, allowing for the controlled and sequential construction of peptides. The Boc (tert-butoxycarbonyl) group provides stability during the synthesis process and can be selectively removed without affecting other functional groups. It is particularly valuable in the development of peptide-based drugs, where precise amino acid incorporation is critical. Additionally, it finds applications in research focused on modifying peptide structures to enhance their biological activity or stability. Its use extends to the study of enzyme inhibitors and receptor ligands, where beta-homophenylalanine derivatives play a key role in mimicking natural substrates or binding partners.
