Crystal polymorphism mic
WebPolymorphism in molecular crystals is a prevalent phenomenon and is of great interest to the pharmaceutical community. The solid-state form is a key quality attribute of a crystalline product. Inconsistencies in the solid phase produced during the manufacturing and storage of drug substances and drug products may have severe consequences. WebCrystal structures and melting point diagrams. Racemic crystals of both 1 and 2 are classified as a “mixed crystal” (i.e., solid solution) composed of two enantiomers. Their stable race-mic crystal structures are almost identical and are called a -form (Figure S2). Only difference between them is that one hy-
