Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical research targeting central nervous system disorders. Its spirocyclic structure and functional groups make it valuable for constructing complex heterocyclic systems found in drug candidates. The bromo substituent allows for further cross-coupling reactions, enabling rapid diversification in medicinal chemistry campaigns. Commonly employed in the development of kinase inhibitors and receptor modulators due to its rigid framework and compatibility with solid-phase synthesis.
