Used as an intermediate in the synthesis of fluorinated pharmaceuticals, particularly non-steroidal anti-inflammatory drugs (NSAIDs). Its difluoroacetic acid structure enhances metabolic stability and lipophilicity, making it valuable in drug design for improved bioavailability. Commonly employed in the preparation of ketoprofen analogs and other arylacetic acid derivatives with analgesic and antipyretic properties. Also utilized in agrochemical research for developing fluorinated active ingredients with increased environmental persistence and biological activity.
