Description of key information

The log Pow is 4.1.

Key value for chemical safety assessment

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

Additional information

The log Pow of Norborene was determined using the HPLC method in a valid experiment according to OECD 117 in a solution of methanol/water =75/25 with a value of 4.1 (exact value: 4.101 +/- 0.002) (Paulus, 2010).

in a second, earlier measurement conducted in acetonitrile/water =70:30 at 40°C the log Pow was determined as 4.0. (Mühlberger, Andert 1994)
