Method:
Partition coefficient was determined by means of shake flask method as per recommendations of OECD 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 6.17.
The average Pow is 0.3772.
The average logPow is -0.4444.
