Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in the synthesis of complex organic molecules. Its boronate ester group facilitates coupling with aryl or vinyl halides under palladium catalysis, making it valuable in pharmaceutical, agrochemical, and materials science research. The presence of the chloro-substituted styryl group allows for further functionalization or modification, enhancing its utility in building conjugated systems such as organic semiconductors or fluorescent compounds. Commonly employed in medicinal chemistry for constructing biaryl scaffolds found in bioactive molecules.
