- At temperature of 25°C, the partition coefficient (Pow) of the test item is 4.63E-04 and and the log Pow is -3.34
- Executive summary:
In this study the partition coefficient of test item in octanol water system was determined by shake flask method.
value ratios of n-octanol to water were as in the below respectively.
The study was conducted at 25 °C and partition coeficient was calculated based on concentrations of the test item in n-octanol and water phases when reached partition equillibrium.
Concentrations of samples were analyzed on LC/MS/MS.
With volume ratio (20:2) of n-octanol to water, the log Pow values were as -3.26 and -3.49
With volume ratio (40:2) of n-octanol to water, the log Pow values were as -3.34 and -3.20
With volume ratio (80:2) of n-octanol to water, the log Pow values were as -3.42 and -3.35
The six log Pow values fall within the allowed range of ± 0.3 units, then the mean log Pow value was -3.34
At temperature of 25°C, the partition coefficient (Pow) of the test item is 4.63E-04 and and the log Pow is -3.34
