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"
