Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No biodegradation study with the test substance is available. A biodegradation study with 2,2’-azobis(isobutyronitrile) was used to fulfill the data gap for the test substance.The underlying hypothesis for the read-across is that the two substances are expected to have similar degradation pathway, where the initial transformation is nitrile hydrolysis. Additional documentation, provided within the IUCLID Assessment Reports section, supports the read-across approach.
In a ready biodegradability study with 2,2‘-azobis(isobutyronitrile), the test substance was degraded 7% after 28 days and 13% after 112 days. The substance is therefore not considered readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- not biodegradable
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.
