Used primarily in peptide synthesis, this compound serves as a protected amino acid derivative. It is particularly valuable in the construction of complex peptides and proteins, where the Boc (tert-butoxycarbonyl) group provides temporary protection for the amine functionality during the synthesis process. This allows for selective reactions at other sites of the molecule without interference. Additionally, it is employed in the development of pharmaceuticals, especially in the creation of peptide-based drugs, where precise control over amino acid incorporation is crucial. Its chloro and homophenylalanine components can also contribute to the biological activity and stability of the final peptide product.
