X-ray structural analysis is a powerful and widespread research method in various fields, for example, in crystallography, chemistry, materials science, etc. In pharmaceuticals, it is used both for research and for quality control. One of the directions is the determination of the qualitative and quantitative phase composition of medicinal substances. Polymorphic forms and hydrates differ in solubility and absorption, therefore it is important to control and evaluate their content during the development and manufacture of drugs.
