Abstract
Savolitinib is a compound that can crystallize in an undesirable, high aspect ratio needle morphology. This morphology type may cause issues in downstream processing. This paper demonstrates a unique method to alter the crystal morphology of savolitinib to make it more processable, resulting in the active pharmaceutical ingredient (API) crystallizing out in considerably more processable stellates. The volatile deep eutectic solvent technique presents a simple and scalable method for changing the crystal morphology while maintaining the polymorph of the API in this case, confirmed via powder X-ray diffraction and differential scanning calorimetry analysis.
