Crystal form identification of dasatinib in tablets / 中国药科大学学报

The aim of this study was to establish the methods to identify crystal form of dasatinib in tablets.X-ray powder diffraction(XRPD)and solid-state nuclear magnetic resonance(ssNMR)were used to analyze the crystal form of dasatinib in Sprycel? tablets and Yinishu? tablets.The results showed that monohydrate and anhydrate were identified in Sprycel? and Yinishu? tablets respectively;with no detectable anhydrate in Sprycel? tablets and no detectable monohydrate in Yinishu? tablets.The results of XRPD and ssNMR were consistent;and could be both applied in the crystal form identification of dasatinib in tablets.
