Description of key information

The log Pow of the test substance was determined in a non GLP study according to OECD Guideline 107 to be -0.5 at 25 °C (BASF AG, 1989).

Key value for chemical safety assessment

Log Kow (Log Pow):
-0.5
at the temperature of:
25 °C

Additional information

Although the study was performed without pH adjustment, supporting data from the KOWWIN calculation (EPI Suite package) revealing a LogKow of -0.42 for the uncharged molecule, confirm that the pH of the experimental study is high enough for having predominantly the uncharged molecule in the test solutions.
