Used in Suzuki-Miyaura cross-coupling reactions to synthesize complex organic molecules, particularly in pharmaceutical and agrochemical research. Its halogen and boronic acid functional groups allow sequential coupling steps, enabling the construction of biaryl and heterobiaryl structures. Commonly employed in drug discovery for modifying aromatic cores to enhance biological activity or pharmacokinetic properties. Also applied in the development of organic electronic materials due to its ability to form conjugated systems.
