Used in peptide synthesis as a protected amino acid derivative, it plays a crucial role in the production of complex peptides and proteins. The Boc (tert-butyloxycarbonyl) group protects the amine functionality, while the 2-Br-Z (2-bromobenzyloxycarbonyl) group safeguards the hydroxyl group of tyrosine. This dual protection allows for selective deprotection and coupling steps, enabling the precise construction of peptide chains. It is particularly valuable in solid-phase peptide synthesis (SPPS), where controlled reactions are essential for creating peptides with specific sequences. Its application extends to research in biochemistry, pharmaceuticals, and biotechnology, aiding in the development of therapeutic peptides, enzyme inhibitors, and other bioactive molecules.
