Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of biaryl compounds in pharmaceutical and agrochemical research. Its boronic acid group enables efficient carbon-carbon bond formation under mild conditions. The presence of chlorine and pyrrolidinyl substituents allows for further functionalization or modulation of electronic properties, making it valuable in the development of active pharmaceutical ingredients (APIs) and functional materials. Commonly employed in medicinal chemistry for building complex aromatic structures with tailored biological activity.
