Used as a key reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in organic synthesis. Its primary application is in the preparation of pharmaceutical intermediates, functional materials, and complex aromatic compounds. The boronate ester group readily transmetallates with palladium catalysts, making it valuable for constructing biaryl structures under mild conditions. Commonly employed in research laboratories for late-stage functionalization in drug discovery and development.
