1,3,3,3-Tetrafluoropropene (HFO-1234ze) is a hydrofluoroolefin. It was developed as a "fourth generation" refrigerant to replace R-134a and as a blowing agent for foam and aerosol applications.[2] The use of R-134a is being phased out because of its ozone-depletion potential and global-warming potential. HFO-1234ez has zero ozone-depletion potential and a low global-warming potential (GWP = 6).[3]
