Reference
Description of key information
The log Pow of the test substance was determined in a non GLP study according to OECD Guideline 117 to be 0.5 at 25 °C, following the HPLC method (Furutani, 1996).
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 0.5
- at the temperature of:
- 25 °C
Additional information
The test was performed at pH 9. Under these test conditions, it is anticipated that the substance is predominantly in its non-ionized form.
