Applicant's summary and conclusion

Conclusions:
the Dissociations Constants of the test item in Water at 23 °C is not measurable
Executive summary:

A determination of the dissociations constant of the test item is not possible because:

 -         Solubility of the test item is to low in water

-         No amines inside which could be deprotonated
