This compound is widely used in peptide synthesis as a protecting group for glutamic acid. The Boc (tert-butoxycarbonyl) group safeguards the amino group, while the Obzl (benzyl) ester protects the carboxyl side chain, and the OMe (methyl) ester protects the C-terminal carboxyl group. It is particularly valuable in solid-phase peptide synthesis (SPPS) to ensure selective deprotection and coupling reactions. Its stability under acidic conditions makes it suitable for sequential peptide assembly. Additionally, it is employed in the preparation of peptide-based drugs, bioactive peptides, and research tools for studying protein interactions and enzyme mechanisms.
