Prediction of Setschenow constants.

The Setschenow (salting out) constant by sodium chloride is related to molar volume, aqueous solubility, and octanol-water partition coefficient, K(ow), of the drug solute. This study validates a previously proposed relationship between the salting out constant of a solute and its partition coefficient. It also shows that the partition coefficient is a better descriptor of salting out than either molar volume or solubility.
