    摘要: The present invention relates to novel crystalline forms of quetiapine hemifumarate, denominated quetiapine hemifumarate form II and quetiapine hemifumarate form III. These novel crystalline forms of quetiapine hemifumarate have been characterized by methods including x-ray powder diffraction (XRD), Fourier transform IR spectroscopy (FTIR), differential scanning calorimetry (DSC), and thermal gravimetric analysis (TGA). Methods for preparation of the novel crystalline quetiapine hemifumarate form II as its chloroform solvate and its dichloromethane solvate, form III as its chloroform solvate, and form I are provided.
