Used in organic synthesis as a boron-based coupling reagent, particularly in Suzuki-Miyaura cross-coupling reactions to form carbon-carbon bonds. Its thiophene and cyclic boronate structure enhances stability and reactivity with aryl halides, making it valuable in the preparation of conjugated organic materials for electronic applications such as organic semiconductors and OLEDs. Also employed in medicinal chemistry for constructing biaryl scaffolds in drug discovery.
