Used in Suzuki-Miyaura cross-coupling reactions to synthesize conjugated organic materials, especially in the development of organic semiconductors and conductive polymers. Its boronic ester group enables efficient carbon-carbon bond formation under mild conditions, making it valuable in pharmaceutical and agrochemical research for building complex heterocyclic systems. Commonly employed in the preparation of thiophene-based functional molecules for optoelectronic devices such as OLEDs and organic solar cells.
