Method
Partition coefficient was determined by means of shake flask method as per recommendations of OECD Guideline 107. Partition coefficient (P) is defined as the ratio of the equilibrium concentrations of a dissolved substance in a two-phase system consisting in two largely immiscible solvents.
Result
Study conducted at 20 °C and at pH of 6.32.
The average Pow is 0.8634
The average logPow is -0.0658
Reference
