This compound is primarily utilized in pharmaceutical research and development as a key intermediate in the synthesis of biologically active molecules. Its structure, featuring a spirocyclic core and a bromophenyl group, makes it valuable for constructing complex drug candidates, particularly those targeting central nervous system disorders. The bromine atom allows for further functionalization through cross-coupling reactions, enabling the creation of diverse chemical libraries for drug discovery. Additionally, its tert-butyl ester group provides stability during synthetic processes, making it a versatile building block in medicinal chemistry.
