Supercritical fluid chromatography (SFC) has gained considerable importance in the area of Separation Science in pharmaceutical analysis over the past few years. The synthesis of chiral compounds is of particular significance in the pursuit of new drug entities. SFC is rapidly replacing high performance liquid chromatography (HPLC) in many pharmaceutical and biotechnological companies as the standard screening and method development tool for chiral compounds. Analysis of pharmaceutical formulations of research compounds is an area where SFC is recently being explored as a possible alternate or complementary technique to HPLC in limited scope. A feasibility study was carried out to perform direct assay of a chiral drug compound AZM in 100% aqueous formulations by SFC. The results indicated that this approach has the potential to significantly reduce the typical sample processing time prior to analysis. The method was reproducible, linear over a wide dynamic range, and sensitive enough to detect the minor enantiomeric impurity in the chiral drug compound investigated here. Further application will be pursued for other research compounds in the future to illustrate the broader applicability of this approach.
