Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

2.82 at 20 °C and pH 13

Key value for chemical safety assessment

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

Additional information

Three literatures cover the log Kow with 2.82.

In a KOWWIN v1.68 calculation (EPISuite v4.11; BASF SE 2015) the n-octanol/water partition coefficient (log Kow) was calculated to be 2.73 at 25 °C. The estimation refers to the uncharged molecule.

As the value of Sangster was determined by shake-flask at pH 13 with GLC analytic, this value was taken as key value.
