Solubility temperature and crystallization
WebSolubility data are used to make crucial decisions from the earliest stages of drug discovery and throughout the entire development process. This white paper covers two dynamic methods for effective and reproducible solubility data generation: the temperature variation and solvent addition methods. These methods can be easily applied by making ... Webrecrystallization solvent is one in which the solid has a very high solubility at high temperatures and a very low solubility at low temperatures. Refer to the flow chart shown on the last page of this handout. Note the distinction between melting and dissolving. Melting is the process that converts a solid to a liquid by supplying heat.
