Tetrafluorosuccinic anhydride is primarily used as a fluorinating agent in organic synthesis, particularly in the preparation of fluorinated compounds. It is valuable in the production of pharmaceuticals, agrochemicals, and specialty chemicals where the introduction of fluorine atoms enhances stability, bioavailability, or activity. The compound is also employed in the synthesis of polymers and coatings, where its fluorinated structure imparts unique properties such as resistance to heat, chemicals, and weathering. Additionally, it serves as a key intermediate in the development of advanced materials, including liquid crystals and electronic components, due to its ability to modify surface properties and improve performance.
