Used in organic synthesis as a key reagent for Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in the preparation of complex organic molecules. Its vinylboronic acid structure with an E-configuration double bond allows for stereoselective synthesis, making it valuable in pharmaceutical and agrochemical research. Commonly employed in the development of bioactive compounds and functional materials where precise molecular architecture is required. Stable under standard handling conditions, it facilitates efficient coupling with aryl or vinyl halides in the presence of palladium catalysts.
