Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the synthesis of biaryl compounds and heterocyclic structures important in pharmaceuticals and agrochemicals. Its boronic ester group facilitates efficient carbon-carbon bond formation under mild conditions. Commonly employed in drug discovery for constructing pyridine-based scaffolds, which are prevalent in kinase inhibitors and other bioactive molecules. Also utilized in materials science for developing organic semiconductors and fluorescent probes due to the electron-rich pyridinone core.
