Used as a reagent in organic synthesis, particularly in the introduction of sulfur pentafluoride groups into aromatic compounds. It is valuable in the development of pharmaceuticals and agrochemicals, where the sulfur pentafluoride moiety can enhance the biological activity of molecules. Additionally, it finds application in materials science for the modification of polymers and other materials to improve their properties, such as thermal stability and chemical resistance. Its role in creating specialized intermediates for further chemical transformations is also notable.
