Widely used in cross-coupling reactions, especially in Suzuki-Miyaura coupling, to introduce pyridyl groups into organic molecules. This reagent enables the formation of carbon-carbon bonds between aromatic halides and the pyridine derivative, making it valuable in the synthesis of pharmaceuticals, agrochemicals, and functional materials. Its boronate ester group is stable and tolerates a variety of reaction conditions, allowing for efficient and selective transformations. Commonly employed in medicinal chemistry for constructing biaryl systems found in drug candidates. Also used in materials science for building conjugated systems in organic electronics.
