Additional information

The partition coefficient of 4'-hydroxyacetophenone was reported in two peer reviewed databases to be log Pow = 1.35 at 25 °C. This attribute was supported by an accepted calculation method used EpiWin with a result of log Pow = 1.2 at 25 °C. Thus a partition coefficient of 1 .35 at 25 °C is regarded to be reliable for 4'-hydroxyacetophenone.
