Used in organic synthesis as a building block for Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical development. Its styryl structure with a boronic acid group allows for efficient coupling with aryl halides, making it valuable in the preparation of conjugated systems such as liquid crystals, fluorescent dyes, and bioactive molecules. The E-isomer configuration supports planarity and electronic conjugation, enhancing performance in materials science applications like OLEDs and organic semiconductors. Also employed in medicinal chemistry for constructing styrene-based analogs in drug discovery.
