Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 substance is not readily biodegradable with 30% degradation observed after 28 days (Bayer, 1999b) and not inherently biodegradable with 18% degradation observed after 28 days (Currenta, 2011a).

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

The inherent degradability was determined on the basis of the oxygen consumption. As the substance contains nitrogen, the result has to be corrected for the oxygen consumed by nitrification rather than by degradation processes. Due to practicability, that oxygen demand was solely determined at termination of the test (day 28) causing a lower degradation as observed on day 27.
