Used as a key reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in organic synthesis. Its primary application lies in pharmaceutical and agrochemical industries, where it serves as a building block for constructing complex aromatic and heteroaromatic compounds. The boronate ester group readily transmetallates with palladium catalysts, making it effective for coupling with aryl or vinyl halides under mild conditions. It is especially valuable in late-stage functionalization due to its stability and selectivity. Commonly employed in research and development of active pharmaceutical ingredients (APIs) and functional materials.
