Used in organic synthesis as an intermediate for pharmaceuticals and fine chemicals. Its structure allows for selective functionalization in cross-coupling reactions, making it valuable in the development of active pharmaceutical ingredients. Commonly employed in palladium-catalyzed reactions such as Suzuki and Heck couplings to build complex naphthalene derivatives. Also utilized in the preparation of dyes, agrochemicals, and specialty polymers due to its stable aromatic framework and reactive bromine site.
