Used in organic synthesis as a building block for pharmaceuticals and agrochemicals, particularly in Suzuki-Miyaura cross-coupling reactions to form carbon-carbon bonds. Its boronic acid group enables coupling with aryl halides, making it valuable in the development of complex aromatic compounds. The presence of both bromo and hydroxy functional groups allows for selective modifications and further derivatization. Commonly employed in the synthesis of bioactive molecules and functional materials where precise substitution patterns are required.
