20 °C

Additional information

The partition coefficient was estimated based on the ratio of the solubilities in n-octanol and in water.

The individual solubilities were carried out by the flask method according to OECD Guideline 105 and the concentration was quantified by UV/Vis absorption.

Since the water solubility of <2µg/L was estimated from the calibration solution with the lowest concentration therefore it can be suggested that the water solubility of 1 µg/L is possibly the lowest measurable concentration and is used as worst-case for the estimation of the log Pow value.
