Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
The Ready Biodegradability IRFMN model of the VEGA platform
predicts that the target compound is NON Readily Biodegradable. There
are some critical aspects related to this output, since the target
compound could be out of the Applicability Domain of the model and the
AD index is 0.433. Only moderately similar compounds with known
experimental value have been found in the training set (see Figure 5):
the most apparently similar compound (Similarity index = 0.73) is a
perfluorinated
compound, presenting however oxygen atom. This model considers molecular
fragments related to Ready Biodegradability (RB). In this case, the
relevant fragment defined by the SMARTS: F has been found “Non RB alert
no. 11 (fluorine)”.
Overall assessment: These results seem to be in agreement with current
scientific evidences, highlighting NON Readily Biodegradability of
fluorinated compounds5,6.
Therefore (1Z)-1,3,3,3- Tetrafluoroprop-1-ene should be considered asNON
Readily Biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
