chlorodifluoromethane

(HCFC-22) CHClF2, this chemical is an intermediate replacement for the old CFCs because it contains a hydrogen atom, making a molecule that is easily attacked by hydroxyl radical in the atmosphere, therefore causing it to have a shorter atmospheric lifetime compared to the CFCs it replaces. In the U. S. HCFC-22's use is already being phased out but the phase out in developing countries like India is stumbling and this may lead to a slower healing of the stratospheric ozone layer's ozone.
