Chlorine monofluoride is a volatile interhalogen compound with the chemical formula Cl F. It is a colourless gas at room temperature and is stable even at high temperatures. When cooled to −100 °C, ClF condenses as a pale yellow liquid. Many of its properties are intermediate between its parent halogens, Cl₂ and F₂.
