Additional information

Two experimental values are available for 2-(4-((5-(trifluoromethyl)pyridin-2-yl)oxy)phenoxy)propanoic acid. One is for the R-enantiomer (Wollerton), the second is for the racemate (Chamberlain); both are equivalent for this endpoint. Both reported values are in very good agreement (to within experimental error), however the values from Wollerton are selected for both dataset consistency, and as they were collected under GLP.
