Chloropentafluoroethane is a chlorofluorocarbon (CFC) once used as a refrigerant and also known as R-115 and CFC-115. Its production and consumption has been banned since 1 January 1996 under the Montreal Protocol because of its high ozone depletion potential and very long lifetime when released into the environment.[3] CFC-115 is also a potent greenhouse gas.

Atmospheric properties

The atmospheric abundance of CFC-115 rose from 8.4 parts per trillion (ppt) in year 2010 to 8.7 ppt in 2020 based on analysis of air samples gathered from sites around the world.[4]

Property Value
Ozone depletion potential (ODP) 0.44[5] (CCl3F = 1)
Global warming potential (GWP: 100-year) 5,860[6] - 7,670[7] (CO2 = 1)
Atmospheric lifetime 1,020[5] - 1,700[6] years
