Reference
The measurement of the dissociation constant (PKa) of the test item at 20°C using a test item concentration of 0.009 mol/l resulted in the following value (rounded mean value of a triple determination): pKa = 9.8
Description of key information
The dissociation constant of the substance is 9.8 at 20°C.
Key value for chemical safety assessment
- pKa at 20°C:
- 9.8
Additional information
A GLP study was conducted (BASF SE 11L00464) in accordance with the OECD Guideline for the Testing of Chemicals 112, dissociation constants in water.
The dissociation constant of the substance was determined to be 9.8 at 20°C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
