trans-1,3,3,3-Tetrafluoropropene, HFO-1234ze(E-isomer), is a hydrofluoroolefin that has the same chemical formula as HFO-1234ze(Z-isomer) and one of many tetrafluoropropene isomers. The HFO-1234ze E-isomer is considered the more useful for refrigeration applications as compared to the HFO-1234ze Z-isomer. It was developed as a "fourth generation" refrigerant intended to replace R-134a, as a blowing agent for foam and aerosol applications, in air horns and gas dusters, and planned use in metered-dose inhalers.
