Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the synthesis of complex aromatic compounds in pharmaceutical and agrochemical research. Its boronic ester group enhances stability and handling compared to the free boronic acid, making it suitable for solid-phase synthesis and parallel reaction screening. The presence of both chlorine and cyano functional groups allows for further selective transformations, facilitating the construction of multi-substituted aromatic systems in drug discovery and materials science.
