Used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions to create complex thiophene derivatives. These derivatives are valuable in pharmaceuticals, agrochemicals, and material science. Acts as a key intermediate for developing bioactive molecules and organic electronic materials. Also employed in the production of conjugated polymers for optoelectronic devices like OLEDs and solar cells. Its boronic acid group enables efficient coupling with aryl halides, making it versatile in constructing carbon-carbon bonds.
