A novel platinum complex,named as saliplatin,was designed,synthesized and characterized with element analysis,coupled inductively plasma-mass spectrum,gravitational thermal-differential thermal analysis,ultraviolet-visible absorption spectrum,infrared spectrum,fast atom bombment mass spectrum and 1H NMR,etc.Its purity was investigated and determined.HPLC-ESI-MS was employed to separate the platinum complex and the impurity,and to identify and quantify the latter.It proved that the impurity in this novel compound was 3,5-diisopropylsalycilic acid,a reactant used in the synthesis of the novel platinum complex,identified with ESI-MS.The mass fraction was determined with HPLC as 4.3%,which meant that the purity of this new substance was 95.7%.
