Widely used in cross-coupling reactions, particularly in Suzuki-Miyaura coupling, this compound serves as a key building block for constructing biaryl and heteroaryl frameworks in pharmaceutical and agrochemical synthesis. Its boronate ester group readily participates in palladium-catalyzed reactions with aryl or heteroaryl halides, enabling efficient formation of carbon-carbon bonds. The presence of a hydroxyl group on the pyridine ring offers an additional site for functionalization or coordination, making it valuable in ligand design and metal-organic frameworks. It is also employed in the development of organic electronic materials due to its ability to tune electronic properties in conjugated systems.
