Description of key information

0% of biodegradation was obtained in a OECD 301B test within 29 days. The C6 pyrazole hemisulfate is not readily biodegradable. 

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

A ready biodegradation test, following the GLP, was conducted on C6 pyrazole hemisulfate according to the OECD 301B Guideline. All the validity criteria were fulfilled and the percentage of biodegradation of the tested substance was 0% at the end of the test (29 days). The C6 pyrazole hemisulfate does not meet the criteria for ready biodegradation.
