Description of key information

pKa 1 = 10.4 at 24 °C
pKa 2 = 8.4 at 24 °C

Key value for chemical safety assessment

Additional information

Since the test item showed more than one change in potential the determination according to OECD Guideline 112 was not possible. Therefore, the dissociation constant was determined

via the Potentiometric titration (HNP method).
