An interesting question for synthesis chemists as the need for reversed-phase flash chromatography for both intermediates and final compounds increases. Historically, normal-phase flash chromatography has been the “go-to” purification tool for synthetic intermediates. Today, however, intermediates and final products are increasingly polar. These polar reaction mixtures cause purification challenges in both separation and recovery with normal-phase (silica) thus requiring use of reversed-phase flash chromatography.
