The octanol/water solubility ratio (So/Sw) was found to be highly correlated with the octanol/water partition coefficient (Kow) of 82 pharmaceutically and environmentally relevant compounds. The solubility ratio gives comparable estimates to that of the group contribution (log P(calcd)) method for estimating the partition coefficient of the compounds used in this study.
