Used as a key intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It plays a significant role in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds to create complex molecules. Its boronic acid group allows for efficient coupling with aryl halides, making it valuable in the development of bioactive compounds. Additionally, it is utilized in the synthesis of thiophene-based derivatives, which are important in materials science for producing organic semiconductors and conductive polymers. Its applications extend to the design of sensors and ligands in catalytic processes.
