Used primarily in organic synthesis as a boronic ester coupling partner in Suzuki-Miyaura cross-coupling reactions. Its boron-containing group enables efficient carbon-carbon bond formation, making it valuable in the preparation of biaryl compounds found in pharmaceuticals, agrochemicals, and functional materials. The carboxylic acid group allows for further derivatization or attachment to other molecules, enhancing its utility in drug discovery and the development of organic electronic materials. It is also employed in the synthesis of complex molecules where selective coupling is required due to its stability and reactivity profile.
