Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The pKa for the test substance is 8.8 at 25ºC.

Key value for chemical safety assessment

Additional information

A literature search has been performed. The dissociating part of the molecule is the same as registered. It is assumed that length of the hydrophobe has no significant effect on the pKa value.

The pKa for the test substance is 8.8 at 25ºC. Furthermore, the pKa is not strongly temperature dependent.
