Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the synthesis of conjugated organic compounds for optoelectronic materials. Its styrylboronate structure allows efficient formation of carbon-carbon bonds, particularly in the development of organic semiconductors, fluorescent dyes, and liquid crystal materials. The compound’s stability and reactivity make it valuable in pharmaceutical and agrochemical research for constructing biaryl and styrene-based scaffolds. Commonly employed in palladium-catalyzed reactions under mild conditions, it supports high yields and selectivity in complex molecule assembly.
