Used in organic synthesis as a building block for Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical development. Its boronic acid group facilitates coupling with aryl or vinyl halides, making it valuable in creating substituted thiophene derivatives, which are common scaffolds in conductive materials, organic semiconductors, and bioactive molecules. Also applied in materials science for designing π-conjugated systems used in organic light-emitting diodes (OLEDs) and sensors.
