Used as a key intermediate in organic synthesis, particularly in the preparation of polycyclic aromatic hydrocarbons and fullerene derivatives. Its strained etheno bridge and reactive bromine site make it valuable in cycloaddition reactions and palladium-catalyzed cross-coupling reactions, enabling the construction of complex organic frameworks for use in materials science, including organic semiconductors and molecular electronics. Also employed in the synthesis of novel carbon-rich structures and nanomaterials due to its rigid, conjugated backbone.
