Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
