Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

HFO-1234yf is phototransformed in the air with ~ 100% degradation observed by 11 days. Based on structure activity analysis, HFO-1234yf would not be expected to hydrolyze in water.

The OH initiated oxidation of CF3CF=CH2gives CF3C(O)F and HCHO in almost quantitative yields. CF3C(O)F is removed from the atmosphere via hydrolysis that occurs at a time scale of about 10 days to give CF3C(O)OH, just like HFC-134a (CF3CH2F). The available data suggest that while CF3C(O)OH is not a natural component of the freshwater environment, it is a natural component of the background oceanic environment, and any additional burden associated with CF3CF=CH2oxidation will be of negligible environmental significance. Similarly HC(O)H decomposes to H2O and CO, the latter oxidizing to CO2in the atmosphere.

HFO-1234yf is not readily biodegradable, has low global warming potential (GWP<1 [based on fifth IPCC assessment]) and will not deplete the ozone (ozone depleting potential = 0).
