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. The presence of chlorine and methoxy substituents allows for further functionalization or modulation of electronic properties in target molecules. Commonly employed in the synthesis of bioactive compounds and functional materials where substituted phenyl rings are required.
