Description of key information

Estimation based on solubility ratio:

log Pow= <-4.5 at 23°C and at pH 10.2

Key value for chemical safety assessment

Additional information

The partition coefficient n-octanol/water (log Pow) can not be determined according to OECD Guideline 107 (shake flask method) as the test item is not a pure substance. The determination of log Pow corresponding to OECD Guideline 117 (HPLC method) is also not applicable, as the test item is a salt and cannot be chromatographed under the prescribed conditions.

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