Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
20 °C

Additional information

A Kow of 0.167 at 20°C, log10 Pow -0.778, was determined using the shake-flask method, designed to be compatible with Method A8 Partition Coefficient of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 107 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.

The dissociation constant of the test item was determined to be 9.30 + 0.12. Since the test item would be in a more ionized form within the environmental pH range of 5 to 9, the partition coefficient of the test item within the environmental pH range of 5 to 9 would, therefore, be less than 0.167, log10 Pow less than -0.778.
