Widely used in cross-coupling reactions, especially in Suzuki-Miyaura coupling, to introduce substituted pyridine moieties into organic molecules. Its boronate ester group readily reacts with aryl or heteroaryl halides in the presence of palladium catalysts, enabling the synthesis of complex pyridine-based structures. Commonly applied in pharmaceutical development, agrochemicals, and materials science where functionalized pyridines enhance biological activity or electronic properties. Stable and easy to handle, it serves as a valuable building block in medicinal chemistry for constructing drug candidates targeting various diseases.
