Hydrogen ordering and new polymorph
Webbility compared to the original crystal form. This new form, referred to as form II, is an example of conformational poly-morphism, which occurs when different conformational iso-mers of a compound crystallize as distinct polymorphs (16). Within weeks this new polymorph began to appear through-out both the bulk drug and formulation areas. Since … WebPolymorphism is quite common for the same material to crystallize in different (more than one) arrangements of molecules in the crystal. Polymorphism can be classified into two …
