Description of key information

The dissociation constants of decamethylenediamine were determined according to OECD guideline no. 112 [adopted on 12 May 1981] with the titration method. A single dissociation constant of pKa = 10.7 (at 24.6 °C) was observed, indicating that the two amino groups have the same strength and have no measurable interaction.

Key value for chemical safety assessment

pKa at 20°C:
