Abstract
The application of chromatographic separation technology in drug intermediate purification aims to solve the problem of impurity removal in drug synthesis and improve the purity of drug intermediate. With the development of modern pharmaceutical industry, the quality requirements for drug intermediates are increasingly strict, and the traditional separation methods are difficult to meet the high purity requirements. Based on the principle of chromatographic separation, advanced HPLC and gas chromatography techniques were used to systematically separate and purify a variety of typical drug intermediates. By optimizing the fixed phase selection, mobile phase matching ratio and operation conditions, a stable and reliable separation system is successfully established. The experimental results show that the chromatographic separation method can effectively remove trace impurities and improve the purity of the target compound to more than 99%, which is significantly better than the traditional crystallization method and extraction method. In particular, the structurally similar isomer separation shows unique advantages.
