Abstract: Objective To study the quantitative analysis methods for chemical reference substances, so as to offer evidence and suggestions for drug quality regulation, drug safety evaluation and drug testing and research institutes that performing the establishment of reference substances. Methods The basic principles, scope, and influencing factors of the cutting-edge quantitative analysis methods of chemical drug standard substances were introduced. The pros and cons between different methods were compared and stated. Results and Conclusion Pharmaceutical Reference substances are the material basis for drug development, quality control testing, safety monitoring and etc., which are crucial to the insurance of the drug quality and the implementation of pharmaceutical specifications. The largest category among Pharmaceutical Reference standards are chemical drug reference substances, which makes the accuracy of their value are of vital importance. The applicability of each method should be fully considered in order to choose the most appropriate method in quantitative analysis of the chemical reference substances.

Key words: chemical drugs, reference substances, quantitative analysis methods, drug testing, primary method, safety evaluation, quality control
