Used in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs), particularly as an intermediate in the production of flurbiprofen. Acts as a key building block in pharmaceuticals due to its ability to enhance drug potency and selectivity. Also employed in the development of liquid crystals for display technologies, where its rigid aromatic structure and fluorine substitution contribute to improved thermal and electro-optical properties. Additionally, finds use in research settings for studying carboxylic acid reactivity in conjugated systems.
