Used in peptide synthesis as a protected histidine derivative, enabling stepwise construction of complex peptides with controlled sequence. Its benzoyl (Bz) group protects the amino terminus, while the methyl ester (OMe) shields the carboxyl end, preventing unwanted reactions. This makes it valuable in pharmaceutical research for developing peptide-based drugs, especially where histidine's imidazole side chain must remain unreactive during coupling steps. Also employed in the synthesis of enzyme inhibitors and bioactive peptides due to its stability and selective deprotection characteristics.
