Description of key information

Adsorption to solid soil phase is expected.

Key value for chemical safety assessment

Koc at 20 °C:
5 190

Additional information

The substance is ionising and therefore the KOC is also dependent on the pH of the medium. Two models were applied to determine the KOC taking into account pH effects.

The maximum KOC is 5190 (BASF Schweiz AG, ACDlabs, 2010) at pH 4 and is used for the CSA and PNEC derivation. The minimum KOC is 425 at pH 9 (Franco and Trapp, 2008).
