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 efficient coupling with aryl halides, making it valuable in the development of complex aromatic compounds. Commonly applied in the synthesis of bioactive molecules and functional materials where substituted phenyl rings are required. The presence of chlorine and methoxy groups allows further functionalization or modulation of electronic properties in target molecules.
