QC(Quality Control ) plays a very important role during the custom synthesis. Certificate of Analysis (COA) will be provided for all these products which characterized using HPLC, MS, NMR spectra, elemental analysis and other testing as requested by our clients. We may ensure our product quality with each production link, including as follows:

• Raw material testing;
• Intermediate compound quality testing;
• Product quality testing;

Our quality control techniques include:

• HNMR(400MHz) (1H, 13C, 19F, 31P);
• M.S.(including G.C./M.S. and HPLC/M.S.);
• Elemental Analysis;
• U.V.;
