| Abstract：Clopidogrel bisulfate is a highly effective antithrombotic drug that inhibits platelet aggregation. It is clinically used to treat heart disease or stroke caused by atherosclerosis. The research of related substances is the key item in the research of drug quality, and it is an important index to evaluate whether the purity of the drug is qualified. Combined with the synthesis route of clopidogrel bisulfate, three potential related substances of clopidogrel bisulfate were analyzed and prepared from the raw materials, intermediates or finished products used in the synthesis process of clopidogrel bisulfate. The structures of three related substances were characterized by 1H NMR, 13C NMR and HRMS. Combined with the monitoring results of three related substances, the process improvement for the synthesis of clopidogrel bisulfate was proposed. |
