Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 = 4.32 -4.62
Key value for chemical safety assessment
- pKa at 20°C:
- 4.62
Additional information
The pKa of the substance was retrieved by the literature in which the dissociation costants and limiting conductances of organic acids in water are reviewed. The pKa was found to be 4.62.
The pKa was also estimated by the use of ChemAxon in which the dissociation costant was predicted to be 4.32.
The dissociation costant obtained in the literature review is used for the chemical safety assessment as it is based on an experimental result In any case the predicted value is very close to the experimental value.
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.
