Used in organic synthesis as a key intermediate for constructing complex molecules, particularly in Suzuki-Miyaura cross-coupling reactions to form carbon-carbon bonds. It is valuable in the production of pharmaceuticals, agrochemicals, and organic materials like conductive polymers. Its boronic acid group enables selective binding to diols, making it useful in sensor development for detecting sugars or other biomolecules. Additionally, it plays a role in the synthesis of thiophene-based compounds, which are important in optoelectronic devices and organic semiconductors.
