Kinetic solubility
WebThermodynamic solubility is most often determined using the equilibrium shake flask method or the pH-metric method. But these methods are time consuming and less preferable at early drug discovery. Solubility determination by dimethyl sulfoxide widely used for kinetic solubility measurement at early drug discovery.
