Description of key information

The calculation for the deprotonation of the acidic component gives: pKa1 = 2.12 and pKa2 = 7.29 (temperature not reported).
The calculation for the deprotonation of the protonated basic component gives: pKa = 12.00 +/- 0.21 at 25°C.

Key value for chemical safety assessment

pKa at 20°C:
2.12

Additional information

HSDB data for the acidic compound: pKa1 = 2.12, pKa2 = 7.29.

The calculation for the deprotonation of the protonated basic component gives: pKa = 12.00

As a consequence the substance exists as a salt of a strong organic acid and a strong organic base, i. e. in ionic form in the environmentally relevant pH range of 4 - 9.
