Applicant's summary and conclusion
- Conclusions:
- The Powand log Powvalue of the test substance:
Nuetral pH:
Pow: 1.6*102- 1.4*103
log Pow: 2.2 -3.1
Ph 2.5:
Pow: 3.8*103
log Pow: 3.6 - Executive summary:
The results of the Rekker claculation method and the HPLC method differ more than 0.3 log units. Since the HPLC method is a more accurate method, the results of this method are reported.
The Powand log Powvalue of the test substance:
