Widely used in organic synthesis as a key reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds between aromatic systems. Its boronate ester group facilitates palladium-catalyzed coupling with aryl halides, making it valuable in the preparation of complex organic molecules, including pharmaceuticals, agrochemicals, and advanced materials. The terphenyl backbone enhances stability and influences electronic properties, which can improve reaction selectivity and yield in conjugated system construction. Commonly employed in research and development for synthesizing liquid crystals, organic semiconductors, and functional polymers.
