Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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