Description of key information

The dissociation constant is determined to 7.6 at 20 °C. It is not possible to separately determine the pka1 and pka2 values for this substance in water. In a supporting study the pKa values are  predicted to 9.98 and 10.16 for the etherdiamine and 4.77 for the acetate. This at a temperature of 25 °C.
