The Log Pow is 3.18 , no data on pH available.
Description of key information
Log Kow: 3.18 at 22.5 °C
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 3.18
- at the temperature of:
- 22.5 °C
Additional information
A log Kowvalue of 3.18 at 22.5 °C was determined by the shake-flask method according to EU Method A.8. In a supporting study by HPLC according to EU Method A.8 it is shown that the log Powvalue is not significantly influenced by the pH value when investigated at pH = 5, 7, 9 and 25 °C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
