摘要
A crystalline form of fluvatinib or fluvatinib methanesulfonate, and a preparation method therefor. The crystalline form I of the fluvatinib has characteristic diffraction peaks as shown in FIG. 1. The crystalline form of the fluvatinib methanesulfonate may take multiple forms, including seven crystalline forms, forms I-VII, wherein crystalline form III has characteristic diffraction peaks as shown in FIG. 9. Said crystalline forms are suited to manufacturing processes for fluvatinib methanesulfonate formulations.
