Used in organic synthesis as a versatile building block, particularly in Suzuki-Miyaura cross-coupling reactions to create complex biaryl compounds. Its boronic acid group enables efficient coupling with aryl halides, making it valuable in pharmaceutical and agrochemical research. The chloro and cyano substituents provide additional reactivity for further functionalization, aiding in the development of diverse chemical structures. Commonly employed in the synthesis of active pharmaceutical ingredients (APIs) and fine chemicals.
