Description of key information

Estimation of Log 10 Dissociation Constant (pKa), using two different QSAR models.

Key value for chemical safety assessment

Additional information

The Log 10 Dissociation Constant (pKa) of the material was estimated using two different QSAR Models. The data is tabulated below.

SPARC yields a value of 16.97.

ACDLabs yields a value of 14.63.

From the two values, it can be summized that the material is not likely to exhibit dissociating activity.
