Used primarily in organic synthesis as a building block for Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical development. Its boronic ester group facilitates efficient coupling with aryl halides under palladium catalysis, making it valuable in the preparation of complex aromatic compounds. Commonly employed in the synthesis of functionalized biaryl structures found in active pharmaceutical ingredients and advanced materials. The carboxylic acid group allows for further derivatization, such as amide formation or esterification, supporting its use in modular synthesis and medicinal chemistry research.
