Description of key information

Dissociation constant pKa = 8.4 (OECD Guideline No. 112)
Literature data: pKa = 8.4 - 8.87

Key value for chemical safety assessment

pKa at 20°C:
8.4

Additional information

The dissociation constant of the substance was determined by means of spectral photometric method according to OECD-Guideline No. 112 to be pKa = 8.4 (standard deviation = 0.1).

The experimental result is supported by literature data.
