Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint summary

Administrative data

Description of key information

For this endpoint sufficient information was obtained from a QSAR analysis showing that there is no evidence for ready biodegradation. This finding is strongly supported by experimental data obtained for structurally highly related compounds from the same chemical class (reactive mesogens) studied in GLP compliant OECD 301F studies. In these experiments no biodegradation was observed.

Overall it is fully justified to conclude that the compound is not ready biodegradable.
