Used as a key intermediate in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions to create complex organic compounds. Its boronic ester group facilitates the formation of carbon-carbon bonds, making it valuable in pharmaceutical research for developing drug candidates. Also employed in material science for synthesizing organic electronic materials, such as polymers and small molecules for organic light-emitting diodes (OLEDs) and other optoelectronic devices. Its stability and reactivity make it a preferred choice in various catalytic processes.
