Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the synthesis of biologically active pyridine derivatives in pharmaceuticals. Its boronic ester group facilitates efficient carbon-carbon bond formation under mild conditions. Commonly applied in the development of kinase inhibitors and other therapeutic agents requiring functionalized heteroaromatic structures. Also employed in medicinal chemistry for constructing libraries of compounds in drug discovery programs due to its stability and reactivity profile.
