Responsible for the research and development of new drugs, including drug molecule design, synthesis, screening, and pharmacology, toxicology, pharmacokinetics and other research; optimize drug performance and safety through experiments and data analysis, and develop innovative drug products; use analytical technology and instrument development to verify analytical methods, and provide quality control and R&D data; responsible for the quality inspection and control of raw materials, intermediates and finished products, and establish a complete quality control system.

Use various analytical techniques and instruments like HPLC, GC, UV, etc., to test drug samples like raw materials, intermediates, finished products, and retained samples, obtaining quality data on components, purity, impurity content, etc. Also participate in developing new analysis methods, designing plans based on drug characteristics and needs, and process, analyze, and count the data to extract valuable information for drug quality evaluation and R&D decisions.
