Used primarily in peptide synthesis as a protecting group for ornithine, ensuring selective reactions during the assembly of peptide chains. The Boc (tert-butoxycarbonyl) group protects the α-amino group, while the Z (benzyloxycarbonyl) group protects the δ-amino group of the ornithine side chain, leaving the carboxyl group free for coupling. This helps prevent unwanted side reactions, allowing for precise control in complex peptide constructions. Commonly employed in the production of biologically active peptides, pharmaceuticals, and research compounds. Its stability under various reaction conditions makes it a reliable choice in organic and medicinal chemistry workflows.
