Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 = 6.52 ± 0.04
Key value for chemical safety assessment
- pKa at 20°C:
- 6.52
Additional information
The measured value is corresponding to the first proton acceptor unit with a pKa of 6.52 ± 0.04 of the conjugated acid. It is assumed, that the second proton acceptor unit has very weak basic properties and can therefore not be detected with the experimental setting in aqueous media.
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.
