Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Estimated value based on solubility ratio:

log Pow= >5.4 <6.4 at 23°C

Measured value by HPLC:

log Pow= >6.5 at 23°C and at pH 6.4

Key value for chemical safety assessment

Additional information

The partition coefficient was measured by HPLC and estimated from the single solubilities in n-octanol and in water.

Further the partition coefficient have been additionally calculated using different programs as recommended in Guideline.

- The calculation by KOWWIN module is given a log Pow value of 5.6.

- The calculated values by ACD/Labs are given as follows:

logD= 6.8 at pH 4-7 at 25°C

logD= 6.5 at pH 9 at 25°C
