Widely used in Suzuki-Miyaura cross-coupling reactions, this compound serves as a key building block for constructing biaryl and heterobiaryl systems in pharmaceutical and agrochemical synthesis. Its boronate ester group readily participates in palladium-catalyzed couplings with aryl halides, enabling efficient formation of carbon-carbon bonds. It is particularly valuable in the development of complex pyridine-containing molecules, which are common motifs in drug discovery. The presence of the phenylpyridine framework also makes it useful in materials chemistry, including the synthesis of organic semiconductors and ligands for metal-organic complexes in catalysis or optoelectronic devices.
