Used in organic synthesis as an intermediate for pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective cross-coupling reactions, making it valuable in the construction of complex heterocyclic compounds for drug discovery. Commonly employed in palladium-catalyzed reactions such as Suzuki and Heck couplings to form carbon-carbon bonds. Also utilized in the synthesis of potential anticancer and antimicrobial agents due to the biological activity associated with iodinated isoquinolines.
