Used primarily as a fluorinated building block in organic synthesis, especially in the development of pharmaceuticals and agrochemicals. Its strong electron-withdrawing properties enhance metabolic stability and bioavailability in active compounds. Commonly employed in the preparation of fluorinated analogs to improve lipophilicity and membrane permeability. Also utilized in specialty polymers and surface treatments where water and oil repellency are required. Its unique fluorine pattern makes it valuable in NMR spectroscopy as a tagging agent.
