Abstract

The present disclosure provides a composition including trifluoroacetyl iodide, at least one organic impurity and at least one inorganic impurity. The at least one organic impurity includes at least one of: difluoroiodomethane, pentafluoroiodoethane, iodomethane, iodopropane, dichlorotetrafluoroethane, dichlorotrifluoroethane, trichlorotrifluoroethane, methyltrifluoroacetate, trifluoroacetic anhydride, difluorobutane and methyl propane. The at least one inorganic impurity includes at least one of: hydrogen iodide, hydrogen chloride, iodine and hydrogen triiodide.
