Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of conjugated organic materials. It enables the formation of carbon-carbon bonds in the preparation of fluorescent compounds, OLED materials, and pharmaceuticals. Its boronate ester group facilitates palladium-catalyzed coupling with aryl halides, making it valuable in medicinal chemistry and materials science. Commonly employed in the development of optoelectronic devices and as a building block in the synthesis of heterocyclic compounds with biological activity.
