- Increased throughput in medicinal chemistry has substantially increased the production of new chiral chemical entities with diverse structural features, requiring fast chiral screening strategies. In an effort to explore screening methods we have developed and evaluated gradients in polar organic and normal phase modes on three popular chiral stationary phases using a sample set of 19 racemic compounds. When compared, gradients performed on par with the isocratic methods besides proving to be advantageous in terms of speed of analysis and elution capacity. MS detection was successfully applied to the analysis of a pooled sample consisting 19 compounds to speed-up the screening process.
