This compound, 3-Carboxy-4-fluorophenylboronic acid, is primarily utilized in organic synthesis and medicinal chemistry as a versatile building block. Its boronic acid group enables it to participate in Suzuki-Miyaura cross-coupling reactions, a key method for forming carbon-carbon bonds, which is essential in the synthesis of pharmaceuticals, agrochemicals, and advanced materials. The fluorine substituent at the 4-position enhances its reactivity and selectivity in these reactions, while the carboxylic acid group at the 3-position provides opportunities for further derivatization, such as esterification or amide formation, making it valuable for creating complex molecules with tailored properties. Additionally, it is employed in the development of boron-based drugs and as a precursor for sensors and probes in biochemical research due to its ability to interact with diols and other biological targets.
