Trifluoromethyl sulphur pentafluoride, CF3SF5, is a rare industrial greenhouse gas,[1] first published in 2000[2] by a group of researchers from Germany, the United Kingdom and the United States.[3] Trifluoromethyl sulphur pentafluoride is considered to be one of the several super greenhouse gases. On a per molecule basis, it is considered to be the most potent greenhouse gas present in Earth’s atmosphere.[4] However, the current concentration of Trifluoromethyl sulphur pentafluoride remains at a level that is unlikely to measurably contribute to earth's warming.[4] The source of the gas is attributed to anthropogenic sources, possibly a by-product of the manufacture of fluorochemicals, originating from reactions of SF6 with fluoropolymers used in electronic devices and in microchips, or the formation can be associated with high voltage equipment created from SF6 (a breakdown product of high voltage equipment) reacting with CF3 to form the CF3SF5 molecule.[4]
