Used as a key reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in organic synthesis. It serves as a stable, air-tolerant boronic ester derivative, ideal for constructing biaryl frameworks found in pharmaceuticals, agrochemicals, and advanced materials. Its electron-rich arylboron structure enhances coupling efficiency with aryl halides under palladium catalysis, making it valuable in drug discovery and development of organic electronic materials.
