Used in organic synthesis as a key intermediate for constructing complex molecules, particularly in Suzuki-Miyaura cross-coupling reactions to form carbon-carbon bonds. Its boronic acid group enables efficient coupling with aryl or vinyl halides, making it valuable in pharmaceutical research for developing drug candidates. Also employed in material science to create conjugated polymers and organic electronic materials, enhancing properties like conductivity and optical performance. Its pyrimidine and thiophene moieties contribute to its utility in designing biologically active compounds and advanced materials.
