Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

A titrimetric determination was performed by BASF AG in 1989. The K(OW) of the tested mixture depends on pH. The result is confirmed by available handbook data.
