Used in organic synthesis as a building block for creating complex molecules, particularly in Suzuki-Miyaura cross-coupling reactions. This reaction is widely employed in pharmaceutical research to form carbon-carbon bonds, enabling the development of drug candidates. It is also utilized in material science for designing organic electronic materials, such as polymers and small molecules for use in organic light-emitting diodes (OLEDs) or organic photovoltaics. Its boronic ester group makes it a versatile intermediate for modifying and functionalizing aromatic compounds.
