Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of complex organic molecules, particularly in pharmaceutical and agrochemical research. Its boronic ester group provides enhanced stability and reactivity, making it suitable for constructing biaryl compounds and functionalized aromatic systems. The presence of both chloro and cyano groups allows for further selective transformations, enabling multi-step synthesis of active pharmaceutical ingredients (APIs) and functional materials. Commonly employed in medicinal chemistry for building blocks in drug discovery programs.
