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 conjugation into larger aromatic systems, useful in materials science for creating organic semiconductors and fluorescent dyes. The E-isomer provides specific spatial orientation that can influence the efficiency and selectivity in synthetic pathways. Commonly employed in research settings for designing sensors and bioactive molecules due to its reactivity and structural stability.
