WebJan 30, 2024 · Recrystallization, also known as fractional crystallization, is a procedure for purifying an impure compound in a solvent. The method of purification is based on the principle that the solubility of most solids increases with increased temperature. WebSolubility is a critical consideration across a wide range of industries. In pharmaceuticals, solubility is an incredibly important parameter needed to achieve the correct drug dosage in the body. Poor solubility is often associated with higher doses needed to reach the correct bioavailability of the drug. Solubility is affected by temperature, the solvent, and the …
