Summary:<\/p>\n

Detecting the crystal polymorph information of APIs in pharmaceutical tablets has been considered extremely difficult using conventional analytical techniques. This is because additives contained in tablets interfere with the desired crystal polymorph signals during various analyses. Therefore, it has not been possible to confirm whether the crystal polymorphism of raw materials has changed before and after formulation (tabletting). In this study, we aimed to solve the above problem by using 3D ED\/MicroED crystal structure analysis, which has been attracting worldwide attention in recent years. Taking advantage of this analysis, “crystal structure analysis can be performed even on complex mixtures,” we succeeded in directly determining the crystal structures of APIs in three pharmaceutical tablets. Furthermore, by comparing these crystal structures with the 3D ED\/MicroED structural information of the before tableting powder, we were able to successfully discuss the changes in crystal polymorphism before and after tableting.<\/p>\n
