Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its protected amine and cyclic amide structure make it valuable for peptide-like scaffolds in medicinal chemistry. Commonly employed in solid-phase and solution-phase synthesis due to the stability provided by the Boc protecting group. Enables selective functionalization at multiple positions for building complex heterocyclic systems found in drug candidates.
