Description of key information
The pKa for the test substance is 8.8 at 25ºC.
Key value for chemical safety assessment
- pKa at 20°C:
- 8.8
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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
