Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Pow = 1540 ± (63.9) and log Pow = 3.19 ± (0.0179) at 25°C, OECD 107, Stulz 1996

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
25 °C

Additional information

The partition coefficient of the substance has been determined using a procedure based on those described in OECD Guideline 107 and EU Method A.8 and the shake flask method. The octanol / water partition coefficient (Pow) expressed also as the logarithm to base 10 (log Pow) was determined to be:


Pow = 1540 ± (63.9) at 25°C

log Pow = 3.19 ± (0.0179) at 25°C


The figure in parentheses represents one standard deviation about the mean value. All values are given correct to three significant figures.
