Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other biologically active molecules. Its functional groups allow for selective coupling reactions, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. Commonly employed in solid-phase and solution-phase peptide synthesis due to the stability and ease of deprotection of the Boc group. Also utilized in the preparation of pyridine-based derivatives for research in drug discovery and biochemical assays.
