We have extensive experience and knowledge in the field of solid-state research, and can provide in-depth analysis and professional advice on test results to help customers effectively solve problems and challenges they encounter.
Drug solid-state research aims to use systematic experimental protocols and advanced solid-state characterization methods to select solid forms (such as polymorph, salt and cocrystal) with the most overall advantages (including stability, bioavailability, process development, etc.). The solid-state characterization is a necessary means to understand the nature of crystal forms and explain the formation of crystal forms, which is of great significance in the pharmaceutical industry. The comprehensive solid-state characterization is not only helpful to analyze the solid form of the drug, but also to identify the differences in physical and chemical properties between different crystal forms. Rational use of various characterization techniques to perform correct solid-state characterization of drugs and understanding the solid-state properties of drugs are qualities that pharmaceutical practitioners should possess.
