Used as an intermediate in organic synthesis, particularly in the preparation of polycyclic aromatic compounds and functionalized naphthalene derivatives. It serves as a building block in the development of pharmaceuticals, agrochemicals, and advanced materials. Its bromine functionality allows for cross-coupling reactions, such as Suzuki or Heck couplings, enabling the formation of carbon-carbon bonds in complex molecule assembly. Also employed in the synthesis of ligands for catalysis and in the production of organic semiconductors due to the extended aromatic system.
