Used in Suzuki-Miyaura cross-coupling reactions to synthesize complex organic molecules, particularly in pharmaceutical and agrochemical research. Its bromostyryl structure enables the formation of conjugated systems important in materials science, such as organic semiconductors and fluorescent probes. The boronic acid group facilitates selective binding in sensor development and can participate in carbohydrate recognition for biological applications. Commonly employed in the preparation of styryl-based derivatives for optoelectronic devices and as intermediates in drug discovery pathways.
