Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of fluorinated active ingredients where enhanced metabolic stability and bioavailability are required. Its structure allows for selective functionalization in cross-coupling reactions, making it valuable in medicinal chemistry for building complex fluorinated aromatic systems. Also employed in materials science for designing specialty polymers with improved thermal and oxidative resistance due to the presence of multiple fluorine atoms and a reactive carboxylic acid group.
