Description of key information

The measurement of the dissociation constant (pKa) of the test item at 20 °C using a test item concentration of about 0.01 mol/l resulted in the following value:

pKa = 5.62 ± 0.03

Key value for chemical safety assessment

pKa at 20°C:
5.62

Additional information

A GLP study was conducted in accordance with the OECD Guideline for the Testing of Chemicals 112. The dissociation constant was determined by potentiometric titration.The measurement of the dissociation constant (pKa) of the test item at 20 °C using a test item concentration of about 0.01 mol/l resulted in the following value: pKa = 5.62 ± 0.03
