Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective functionalization at multiple sites, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in the preparation of proteolysis-targeting chimeras (PROTACs) due to its ability to link E3 ligase ligands with target protein binders. Also utilized in the construction of piperidine-based scaffolds found in neurodegenerative disease research and anticancer agents.
