Reference
Endpoint:
dissociation constant
Type of information:
(Q)SAR
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
accepted calculation method
Justification for type of information:
The calculation is done by a decision tree for prediction of pKa for small molecules based on a set of SMARTS strings, pKa-SMARTS OpenTox.
Principles of method if other than guideline:
The calculation is done by a decision tree for prediction of pKa for small molecules based on a set of SMARTS strings, pKa-SMARTS OpenTox.
GLP compliance:
not specified
Specific details on test material used for the study:
- Name of test material (as cited in study report): sodium 2-(methylamino)ethanesulfonate
Dissociating properties:
yes
pKa:
8.66
Remarks on result:
other: estimated by SMART-pKa model
Conclusions:
The pKa is predicted to be 8.66 using the SMART-pKa model by OpenTox.
Executive summary:

The given pKa of 8.66 is calculated by using the SMART-pKa model. We consider this value as reliable approximation of the pKa for sodium N-methyltaurinate, since experimental data have not been observed.
