Description of key information
Estimation by (Q)SAR prediction of pKa 9.99 at 25 °C. The error of prediction (based on validation data) is +/- 0.4 pKa units.
Key value for chemical safety assessment
- pKa at 20°C:
- 9.99
Additional information
QSAR prediction according to SPARC (SPARC Performs Automatic Reasoning in Chemistry) 2009 release w4.5.1529-s4.5.1529 model. Uncertainties in the estimated value are not expected to affect the safety assessment or safe handling of the substance based on the intended uses under the EU REACH Regulation.
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.
