Used in organic synthesis as a key intermediate for pharmaceuticals and agrochemicals, particularly in the development of bioactive molecules targeting kinase inhibition. Its spirocyclic structure and bromo-vinyl functionality make it valuable in cross-coupling reactions, enabling the construction of complex heterocyclic systems. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its rigid scaffold and potential for functionalization. Also applied in materials science for designing novel organic semiconductors with tailored electronic properties.
