Description of key information

Due to the low log pO/W a study is not requested. Two QSAR-calculations are available and reported.

Key value for chemical safety assessment

Koc at 20 °C:
97

Additional information

The log Koc of the substance was calculated by KOCWIN Program (v2.00). Due to the estimated Log Koc = 0.9553, adsorption of the substance to soil is not to be expected.

In a second study the estimation was performed based on a water solubility of 139 mg/l at pH 10 (Pharmacon Europe Report No. 47595) using regression equations (Lyman, Reehl, Rosenblatt: Handbook of Chemical Property Estimation Methods, 1990) relating the Koc with the water solubility. Furthermore, the molecular weight of the substance, i.e. 442.7 g/mol was used. The adsorption coefficient of the substance was determined by calculation. It resulted in a Koc value of 97 meaning that the substance is considered as moderately mobile in soils.
