Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules and drug candidates. Its spirocyclic structure and functional groups make it valuable in medicinal chemistry for constructing complex heterocyclic systems. Commonly employed in the preparation of kinase inhibitors and other therapeutic agents where structural rigidity and specific stereochemistry are required. Also utilized in research settings for scaffold diversification in combinatorial chemistry and library generation for high-throughput screening.
