Description of key information

pKa values are calculated for the two constitutents of the substance:

- EC 500-029-3: pKa 12.8 - 14.8

- EC 500-044-5: pKa 13.7 - 15.1

Key value for chemical safety assessment

pKa at 20°C:
12.8

Additional information

pKa values from the two constituents of the substance are calculated giving that undissociated molecules can be expected at environmentally relevant pH values of 4 -9.
