Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. Its spirocyclic structure and bromine functionality make it valuable for constructing complex heterocycles through cross-coupling reactions. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies, especially in optimizing dopamine or serotonin receptor modulators. Also utilized in the preparation of bioactive molecules where rigid scaffolds enhance binding selectivity and metabolic stability.
