Description of key information

The pKa 1 for the test substance is 10.62 and the second pKa is 8.64 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 1 for the test substance is 10.62 and the second pKa is 8.64 at 25ºC.
