(2-Formyl-5-(trifluoromethyl)phenyl)boronic acid is primarily used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions. This reaction is widely employed in the pharmaceutical industry to create carbon-carbon bonds, which are essential for constructing complex molecules, including drug candidates. The presence of the boronic acid group makes it a valuable reagent for coupling with aryl halides, enabling the synthesis of biaryl compounds. Additionally, the trifluoromethyl group enhances the compound's reactivity and stability, making it useful in the development of agrochemicals and advanced materials. Its application extends to the preparation of intermediates for bioactive molecules, where the formyl group can be further functionalized to introduce additional complexity.
