Abstract: Chiral preparative chromatography is a technology increasingly used in the pharmaceutical industry to deliver enantiomerically pure drug candidates. A strategy for rapid screening of conditions on polysaccharide chiral stationary phases (CSPs) has been developed with an emphasis on preparative applications. Sample solubility is a major limiting factor in preparative chromatography. Most reported analytical chiral separations on polysaccharide CSPs are with eluent systems consisting of mainly hexane and small amounts of alcohol as a modifier. The intelligent chiral resolution system (ICRS) was developed to emphasize polar solvents as the first choice for eluent systems. Examples of this approach, and details on the screening procedure are presented. Using the system, chiral preparative procedures can be developed for most compounds in approximately 3 hours.
