This chemical is primarily used in peptide synthesis as a building block for creating more complex peptide structures. It is particularly valuable in solid-phase peptide synthesis (SPPS) due to its Boc (tert-butyloxycarbonyl) protecting group, which can be selectively removed under acidic conditions without affecting other functional groups. The Asp(OBzl) moiety, with its benzyl ester protection, ensures the carboxyl group of aspartic acid remains intact during the synthesis process. The Phe (phenylalanine) residue contributes to the overall hydrophobicity and structural integrity of the peptide. This compound is often employed in the development of pharmaceutical peptides, bioactive molecules, and research tools for studying protein interactions and enzyme mechanisms. Its precise structure allows for controlled peptide elongation, making it a key component in the synthesis of peptides with specific sequences and functions.
