4-Carboxylphenylboronic acid pinacol ester (CAS 180516-87-4)

4-Carboxylphenylboronic acid pinacol ester plays a pivotal role in material science and organic chemistry research due to its stability and reactivity. Its primary application is as a reagent in the Suzuki-Miyaura cross-coupling reactions, which are instrumental in constructing biaryl compounds with precision. The boronic ester moiety specifically interacts with palladium catalysts to facilitate the formation of carbon-carbon bonds, an essential process for synthesizing a variety of complex organic molecules used in OLEDs, liquid crystals, and other electronic materials. Researchers also utilize the carboxyl functional group for post-coupling modifications, such as creating carboxylic acid derivatives, which are key intermediates in the production of dyes, pigments, and polymers with specific light absorption properties. Additionally, this compound is utilized in the creation of boronic acid-based sensors that can detect saccharides and other diol-containing biomolecules, making it useful in the design of diagnostic tools and the study of biological recognition processes.
