Description of key information

LogPow= -5.3 at 20°C at pH 7
(estimated based on individual solubilities)

Key value for chemical safety assessment

Additional information

Due to the fact of the differences in the solubility of the testitem in water and in n-octanol the determination of the log Pow corresponding to the OECD Guideline 107 (shake flask method) is not feasible. Because the test item cannot be chromatographed under the prescribed conditions the HPLC-method (OECD Guideline 117) is also not feasible.

Due to this, the log Pow can only be estimated from the single solubilities of the test item in water and in n-octanol.

The determination was done according to OECD Guideline 105, flask method. The pH value is referred to the water solubility.
