Abstract
This invention discloses a novel technology for the impurities assay of TRODAT-1 raw material by reverse phase high performance liquid chromatography (RP-HPLC). The method for TRODAT-1 raw material impurities assay of this present invention includes using high performance liquid chromatography (HPLC), liquid chromatography tandem mass spectrometry (LC-MS/MS), HPLC column, preparation of samples, regents and eluent as well as performing parent and product ion analysis by mass spectrometry for the method validation, calculation of chromatography resolution and raw material impurities. This invention is the first report in the world that proved the existence of oligomers in TRODAT-1 raw material as well as an elaborated analysis through validation procedures.
