Description of key information

Log Pow= 4.5 at 25°C and at pH 7

Key value for chemical safety assessment

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

Additional information

The test was performed by the shake flask method according to EEC Directive 84/449, A.8.

Due to at least 6 basic amine groups with pKa's near 10, the logP depends strongly on pH. LogP's were measured in the accessible pH-range ( 7.0) at 3 different pH (7.0, 6.0, and 5.2). The enclosed figure allows extrapolation within a certain range.

log Pow= -0.065 at pH 6.0

log Pow= -0.94 at pH 5.2
