Used primarily in the synthesis of perfluorohexyl compounds for applications in pharmaceuticals and agrochemicals. Acts as a key intermediate in the preparation of fluorinated building blocks used in drug discovery due to the metabolic stability imparted by the perfluoroalkyl group. Employed in the development of contrast agents for medical imaging, particularly in blood substitutes and oxygen carriers, owing to its high gas solubility. Also utilized in the formulation of water- and oil-repellent coatings for textiles and electronics, and as a component in specialty fluids for electronic testing and heat transfer applications. Its chemical inertness and thermal stability make it suitable for use in extreme environments.
