Used in peptide synthesis as a protected amino acid derivative, enabling stepwise construction of peptides with controlled stereochemistry. The Z (benzyloxycarbonyl) group acts as an amine protecting group, while the methyl ester (OMe) protects the carboxylic acid. This allows selective deprotection and coupling in solid-phase or solution-phase peptide synthesis. Commonly employed in the preparation of peptide intermediates for pharmaceuticals and biochemical research. Stable under a variety of reaction conditions, making it suitable for multi-step syntheses.
