Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other biologically active molecules. Its structure allows for selective functionalization in multi-step organic reactions, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in peptide coupling and protection strategies due to the Boc (tert-butoxycarbonyl) group, enabling controlled amine reactivity. Also utilized in research settings for labeling and conjugation in biochemical assays.
