Used in peptide synthesis as a protected amino acid building block, particularly in the development of bioactive peptides and pharmaceuticals. The Boc (tert-butoxycarbonyl) group provides temporary protection of the amino functionality, allowing selective reaction at other sites during solid-phase or solution-phase synthesis. The 3,5-dibromo substitution on the aromatic ring enhances steric and electronic properties, useful in structure-activity relationship studies or in promoting specific conformational features in peptides. Commonly applied in research settings for designing enzyme inhibitors, receptor ligands, or labeled peptides where halogen atoms can serve as handles for further modification via cross-coupling reactions.
