Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment

Additional information

In the key study (Ciba-Geigy, 1985), the ready biodegradability of the test item was assessed over a 28 day period by the modified Sturm test (OECD 301B). The nominal test concentrations were 10 and 20 mg a.s./L. The test material attained up to 42 and 46 % biodegradation after 28 days whereas the positive control substance (Aniline) was 100 % degraded 28 days. Therefore, the test substance is not readily biodegradable according to OECD criteria. it is moderately/partly biodegradable.

The Chemical Oxygen Demand of the test item was determined to be 1.86 g COD/g.
