Description of key information


Key value for chemical safety assessment

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

Additional information

A test has been performed on the substance following OECD 107, but no reliable result has been obtained, since the peak of the substance in HPLC is recorded before the reference peak. The only conclusion from the experimental test is that Log Kow is < 4, but an estimation performed with KOWWIN v.1.68 set the log Kow of the substance < 2.9.

In order to fully assess the potential logKow of the substance a compairison with analogue substance 2 is taken into consideration and the value experimentally obtained for it is applied also to the target substance, i.e. logKow equal to -1.7 at 25°C and pH 4.5
