The values for the octanol-water system in the following table are from the Dortmund Data Bank. They are sorted by the partition coefficient, smallest to largest (acetamide being hydrophilic, and 2,2,4,4,5-pentachlorobiphenyl lipophilic), and are presented with the temperature at which they were measured (which impacts the values).
Values for other compounds may be found in a variety of available reviews and monographs. Critical discussions of the challenges of measurement of log P and related computation of its estimated values (see below) appear in several reviews.
