Description of key information

The Log Koc was determined  for T = 25 °C as 2.1 (unprotonated molecule) by QSAR. In the environmental relevant pH range, theLog Koc value drops sharply with falling pH values as consequence of the protonation process.

Key value for chemical safety assessment

Additional information

The Log Koc was estimated with PCKOCWin and ACD/LogD Suite. The results obtained with both methods for the unprotonated specie were 1.69 and 2.1 and showed a good agreement. Only with the ACD/LogD Suite program it is possible, to describe the partition behaviour in dependence on the pH value.
