Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for building complex heterocyclic systems. The Boc-protected amine group enables controlled deprotection and coupling reactions, facilitating peptide-like chain elongation or attachment to scaffolds in drug design. Commonly employed in research settings for creating libraries of compounds in high-throughput screening.
