WebOct 15, 2015 · 4. Polymorph Screening The polymorph screening process seeks to determine whether a given compound exists in polymorphic forms [50]. In recent decades, several techniques have been developed to improve the polymorph screening of drugs. The concept of crystal engineering was introduced by Pepinsky in 1955 [51] and first applied by WebIf T t is located below the melting points of both polymorphs, the two polymorphs are said to be enantiotropes, and the polymorphic system is said to exhibit enantiotropy or to be enantiotropic in nature.A representative phase diagram for an enantiotropic polymorphic system is shown in Fig. 2.2a.Below T t, Polymorph I is more stable.Above T t, Polymorph …
