Description of key information

The pKa of isophorone diamine was calculated with the Solaris V4.67 software of Advanced Chemistry Development  (ACD) as 10.72. This is in reasonable agreement with a pKb of 3.6: pkA + pKb = 14.32 which is close to the theoretical value of 14.0.

Key value for chemical safety assessment

pKa at 20°C:
10.7
