Used in organic synthesis as a protected amino acid derivative, particularly in peptide coupling and heterocycle formation. The Boc-protected amine group allows selective reactivity at the carboxylic acid site, making it valuable in medicinal chemistry for building complex molecules. Commonly employed in the synthesis of pharmaceutical intermediates, especially kinase inhibitors and other bioactive compounds containing pyridine scaffolds. Its structure supports solid-phase synthesis and is compatible with standard coupling reagents like HATU or EDC.
