Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals, particularly in the development of spirocyclic compounds with biological activity. Its bromine functionality allows for cross-coupling reactions, enabling the construction of complex molecular architectures. Commonly employed in medicinal chemistry for structure-activity relationship studies due to the rigid spiro framework, which can enhance metabolic stability and target selectivity. Also explored in materials science for designing chiral ligands and optoelectronic materials.
