2,3,3,3-Tetrafluoropropene, HFO-1234yf, is a hydrofluoroolefin (HFO) with molecular formula CH 2 =CFCF 3. Its primary application is as a refrigerant with low global warming potential (GWP). [ 1][ 2] As a refrigerant, it is designated R-1234yf[ 1] and marketed under the names Opteon YF by Chemours and as Solstice YF by Honeywell. [ 3]
trans-1,3,3,3-Tetrafluoropropene (HFO-1234ze (E), R-1234ze (E)) is a hydrofluoroolefin. It was developed as a "fourth generation" refrigerant to replace fluids such as R-134a, as a blowing agent for foam and aerosol applications, and in air horns and gas dusters. [ 3] The use of R-134a is being phased out because of its high global warming ...
1,3,3,3-Tetrafluoropropene. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). 1,3,3,3-Tetrafluoropropene is a hydrofluoroolefin which has two isomers: cis -1,3,3,3-tetrafluoropropene. trans -1,3,3,3-tetrafluoropropene, used as a refrigerant (R-1234ze (E).)
Hydrofluoroolefin. Chemical structure of 1,3,3,3-tetrafluoropropene (HFO-1234ze) Hydrofluoroolefins (HFOs) are unsaturated organic compounds composed of hydrogen, fluorine and carbon. These organofluorine compounds are of interest as refrigerants. Unlike traditional hydrofluorocarbons (HFCs) and chlorofluorocarbons (CFCs), which are saturated ...
cis. -1,3,3,3-Tetrafluoropropene. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). cis-1,3,3,3-Tetrafluoropropene (HFO-1234ze (Z), R-1234ze (Z)) is a hydrofluoroolefin which has been considered for use as a refrigerant in high-temperature heat pumps.

Tetrafluoropropene. Tetrafluoropropene, also called tetrafluoropropylene, has the following isomers: This is a gaseous phase effluent from the decomposition of Teflon when laser cutting it. [1]
ETS transcription factor family. Structure of Ets-1 DNA binding autoinhibition. [ 1] In the field of molecular biology, the ETS ( E26 transformation-specific[ 2] or E-twenty-six. (Erythroblast Transformation Specific)[ 3]) family is one of the largest families of transcription factors and is unique to animals. There are 28 genes in humans [ 4 ...
