Description of key information

Estimated (by Hanmett Correlation Method) pKa values: -3 (Triazin sites) and 9.4 (Phenol sites).

Key value for chemical safety assessment

pKa at 20°C:
-3

Additional information

It has been estimated, according to the Hammett correlation method, that the substance is not dissociated or protonated in the environmentally relevant pH range of 5 to 8. Estimated pKa values of -3 and 9.4 were determined for the triazin (3x) and phenol (2x) sites.
