The products are characterized by 1H-NMR,MS and HPLC.The resulted SPC is labeled with 131I in a labeling yield of 71.2% and with radiochemical purity of more than 98% after HPLC purification.There are no significant changes in the radiochemical purity for 131I-SIPC after 72h storage at room temperature.展开更多
