Used as a key intermediate in the synthesis of nonsteroidal anti-inflammatory drugs (NSAIDs), particularly in the production of naproxen derivatives. Its structure allows for efficient transformation into active pharmaceutical ingredients with enhanced metabolic stability and bioavailability. Commonly employed in research and development of analgesic and antipyretic agents. Also utilized in the preparation of fluorinated organic compounds where the trifluoromethyl group improves lipophilicity and resistance to oxidative degradation.
