Applicant's summary and conclusion

Executive summary:

The n-octanol/water partition coefficient of ZK 34517 was determined according to EU Testing Guideline A.8 (HPLC method based on OECD guideline no. 117) to be

log Pow = 2.06 (95 % confidence limits 1.84 - 2.28)

which indicates considerable lipophilicity. The method is based on the correlation of the reversed phase retention data of the test compound with those of reference compounds with known log Pow values.
