log Pow
Partition coefficient:
5.1
Temp.:
20 °C
pH:
2 - 10

Applicant's summary and conclusion

Conclusions:
logPow = 5.1 (at 20°C for pH range 2-10)
Executive summary:

The partition coefficient (n-octanol/water) of the test substance was determined in a GLP study according to EU method A.8. No substance was detectable in the aqueous phase using UV spectroscopy. Calculation was done by the method of Rekker, Hansch Leo and is valid for the pH

range 2-10. The log Pow was determined to be 5.1 at 20°C.
