Description of key information

Log Kow = 4.5 at 24-24.6°C

Key value for chemical safety assessment

Log Kow (Log Pow):
4.5
at the temperature of:
24 °C

Additional information

The experimentally derived logPow is 4.50. This result was supported by QSAR calculation which resulted in a log Pow of 4.48. Furthermore the QSAR-tool refered to a further experimental result of 4.92. For the risk assessment the experimentally determined logPow of 4.50 will be used.
