key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
Justification for type of information:
This value is derived using an accepted calculation method.
Qualifier:
according to guideline
Guideline:
other: QSAR model
Principles of method if other than guideline:
Structure-based QSAR property prediction by means of linear free energy relationships and molecular orbital properties.
This value is derived using an accepted calculation method.
GLP compliance:
no
Remarks:
not applicable. QSAR model
Dissociating properties:
yes
No.:
#1
pKa:
0.7
Temp.:
20 °C
Remarks on result:
other: Strongest pKa(Acid): 0.70 +/- 0.50

An estimated pKa of 0.7 indicates that this acid is fully dissociated in the environmental pH range 4 to 9.
