Cas Number:
84961-74-0
IUPAC Name:

Results and discussion

Partition coefficient
Type:
log Pow
Partition coefficient:
> 0.51
Temp.:
20 °C
Remarks on result:
other: Determined by ratio of solubilities in n-octanol and water
Details on results:
The solubility in n-octanol was determined to be >750 g/L at 20 degC. The water solubility was determined to be >230 g/L. Therefore the Pow is calcuated as >750/230 = > 3.26. Therefore the log Pow is >0.51

Applicant's summary and conclusion

Conclusions:
The substance has a log Pow of >0.51
