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 provides electronic and steric properties that influence reactivity and selectivity in synthesis. Commonly employed in the preparation of bioactive molecules and functional materials requiring specific substitution patterns on aromatic rings.
