Used as an intermediate in organic synthesis, particularly in the development of advanced materials and pharmaceuticals. Its spirocyclic structure with a bromine functional group makes it valuable for cross-coupling reactions, enabling the construction of complex polycyclic frameworks. Commonly employed in the synthesis of organic semiconductors, light-emitting diodes (OLEDs), and photovoltaic materials due to its rigid backbone and electronic properties. Also explored in medicinal chemistry for designing novel bioactive compounds where steric hindrance and 3D architecture are advantageous.
