TLC is a commonly used method development tool for flash purification. Product mixtures separated using TLC generally can be purified by flash chromatography using the identical solvent system.
Thin-layer chromatography (TLC) is a commonly used method development tool for flash purification. Product mixtures separated using TLC generally can be purified by flash chromatography using the identical solvent system. The method transfer accuracy of TLC to flash is based on the TLC silica and flash silica properties. When identical, the equation 1/Rf = CV holds, where Rf is the retention factor of a compound separated by TLC, and CV is the number of column volumes required to elute a compound. Cartridge loading capacity is based on the difference in CV (DCV) between two adjacent compounds.

Flash purification involves a simple liquid chromatography technique
» Method development uses TLC as a way of deciding the parameters for the
separation
» Isocratic separations are easiest to develop, but gradient separations are
more powerful
» Software in the Isolera helps with conversion of an isocratic separation to
a gradient
» It is possible with the Spektra software to run step gradients
» Loading options are dependent on the column type
» SNAP offers the most flexibility
» Care must be taken to choose the best loading option to get good
purifications

Flash Chromatography is the primary tool used by medicinal chemists for reaction mixture purification. Over the past 10 or so years, the use of reversed-phase flash chromatography for reaction mixture purification has increased dramatically due to both chromatographic and non-chromatographic reasons.

TLC to flash method transfer accuracy is improved when TLC plates and flash cartridges with identical silica from Biotage are used. For synthetic chemists, the benefits of matched TLC plates and flash cartridges are better purification throughput, increased compound purity and yield, and reduced solvent cost.
