What is Polymorphism Phenomenon?

Polymorphism phenomenon refers to the phenomenon that the same compound forms different crystalline forms due to various arrangement forms and molecular conformations. Different crystalline forms of APIs may have different physical and chemical properties, which may affect the stability of APIs and formulations, the production process of formulations, solubility, and bioavailability, etc., and thus may affect the safety, efficacy, and quality control of drugs.

Therefore, the study of the possible influence caused by APIs' polymorphism and APIs' crystal structure is the core of the core element and key link to ensure the quality of drugs, and is of great significance to the development of chemical generic drugs.
