Optimizing the Purification of a Chiral Compound Utilizing a Benchtop Semi-Preparative to Preparative HPLC System

There are often significant differences in the effectiveness and toxicity of drug enantiomers in biological systems. This has led to the need for the separation of chiral drug candidates into their respective enantiomers.

There are often significant differences in the effectiveness and toxicity of drug enantiomers in biological systems. This has led to the need for the separation of chiral drug candidates into their respective enantiomers. Semi-preparative and preparative chromatography has become a common tool for the separation of chiral enantiomers. This application note describes the chiral separation of trans-Stilbene oxide (Figure 1) using a multi-purpose, benchtop, preparative chromatography system that is capable of separating compounds by normal-phase or reverse-phase HPLC at flow rates of up to 100 mL/min.

Experimental Conditions
