Used in peptide synthesis as a protected amino acid derivative, enabling selective coupling and chain elongation in the production of complex peptides. The Boc group provides temporary protection of the alpha-amino function, while the Z (benzyl) group protects the side-chain amine of the Dab residue, allowing orthogonal deprotection strategies. The hydroxyl group at the C-terminus can be activated for esterification or used in solid-phase linkage. Commonly applied in the synthesis of bioactive peptides and peptidomimetics where stereochemical control and side-chain functionality are critical. Suitable for use in both solution and solid-phase peptide synthesis protocols.
