Used as a key intermediate in the synthesis of fluorinated pharmaceuticals and agrochemicals due to its highly electron-deficient aromatic ring, which facilitates nucleophilic aromatic substitution reactions. Its ester group allows for easy transformation into carboxylic acids, amides, or other derivatives, making it valuable in medicinal chemistry for building bioactive molecules with improved metabolic stability and membrane permeability. Also employed in the development of liquid crystals and functional materials where fluorine substitution enhances thermal and chemical resistance.
