Product formulators and regulatory agencies are well aware that different polymorphs and hydrates of a given compound can influence product performance and safety. Another driving force for developing sensitive methods for detecting API crystal modification in formulated products is intellectual property.
This publication Combined impactor and x-ray diffraction (XRPD) methodology for characterizing polymorph impurities in inhalation powders presents a combined impactor and XRPD methodology for characterising polymorph impurities in inhalation powders.
