Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

A solution of Structural Analogue 01 in a mineral medium was inoculated and incubated for 28 d under aerobic conditions. During this period the ready biodegradability is determined.


Structural Analogue 01 showed:

0% degradation after 4 days. 

1% degradation after 6 days.

1 % degradation after 8 days.

1% degradation after 12 days.

3% degradation after 14 days.

4% degradation after 18 days.

3 % degradation after 20 days.

2% degradation after 22 days.

3% degradation after 26 days.

5% degradation after 28 days


Therefore the test substance, by analogy of read across, has to be classified as "Not Readily Biodegradable"
