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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Reference
No evaluation possible
The resulting suspension was titrated with NaOH respectively HCl standard solution, measuring the pH during the titration. No evaluable inflexion point was found
Description of key information
not detectable
Key value for chemical safety assessment
Additional information
The pKa of the substance could not be determined experimentally. The pKa values were calculated to be 15.45, 4.89, -0.87 and -19.65 at 25°C (ACD/pKa, version 12.00; Advanced Chemistry Development, Inc: 2008)
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.
