Description of key information

The pKa value of the substance is 14.02 ±0.10 (calculated with the software ACD/pKa v 7.0 at a simplified structure of the test item for 25 °C). Therefore the undissociated form (protonated form) exists at a pH value < 13 (Currenta, 2008).

Key value for chemical safety assessment

pKa at 20°C:
14.02
