Scope and limitations of solid-supported liquid-liquid extraction for the high-throughput purification of compound libraries.
This paper reports some of the advantages and limitations of solid-supported liquid-liquid extraction (SLE) for the rapid purification of organic compound libraries. Issues of solvent compatibility, compound compatibility, and technical methods are addressed. In addition the prospective use of calculated log P values is investigated to determine which impurities will be effectively removed by this technique. In addition SLE is shown to be complementary and in some cases superior to solid-phase extraction (SPE) methods for library purification. This is especially true when the desired products have functionality equivalent to that of the impurity to be removed.
