Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
pKa calculations (Perrin calculation method):
pKa values for the cation : 15.1 (pKa acid), and 9.4 and -3.8 (pKa basic).
pKa values for the anion : 3.6, 4.0, 4.7 and 5.1 (pKa acid), and 8.5, -0.3 and -0.9 (pKa basic).
Key value for chemical safety assessment
Additional information
The substance is an aqueous solution of an organic salt. The salt is completely dissociated. As the dissociation of the salt is not an equilibrium the dissociation constant cannot be determined by an experimental method such as the titration method or the spectrophotometric method.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
