Used as a key intermediate in the synthesis of fluorinated pharmaceuticals, particularly antifungal agents such as fluconazole and related triazole derivatives. Its difluorinated aromatic and acetic acid structure enables enhanced metabolic stability and bioavailability in final drug compounds. Commonly employed in medicinal chemistry for constructing fluorinated building blocks that improve lipophilicity and binding affinity to target enzymes. Also utilized in agrochemical research for developing fluorinated pesticides with improved environmental persistence and activity.
