Description of key information

According to literature sources, the pKa values for the first protonation of 1,2-Diaminocyclohexane range from 9.77 to 9.94 at 20-25 °C and the pKa values for the second protonation range from 6.13 to 6.47 at at 20-25 °C.
According to the calculation by the online available SPARC tool, the pKa value for the first protonation of 1,2-Diaminocyclohexane is 10.35 and the pKa value for the second protonation of 1,2-Diaminocyclohexane is 7.1.

Key value for chemical safety assessment

Additional information

According to literature sources, the pKa values for the first protonation of 1,2-Diaminocyclohexane range from 9.77 to 9.94 at 20-25 °C and the pKa values for the second protonation range from 6.13 to 6.47 at at 20-25 °C.

According to the calculation by the online available SPARC tool, the pKa value for the first protonation of 1,2-Diaminocyclohexane is 10.35 and the pKa value for the second protonation of 1,2-Diaminocyclohexane is 7.1.

These values are similar enough to give a reliable estimate of the range of pKa values of the submission substance.
