Development of a tripartite solvent blend for sustainable chromatography

Abstract

A three-component solvent system (isopropyl acetate, methanol, and heptane) was designed to empower routine chromatographic separation of a wide range of compounds, from polar to nonpolar molecules, without the need for undesired chlorinated solvent. This system was evaluated with a pharmaceutically-relevant set of compounds via practical silica gel chromatographic purification, making the solvent blend an attractive sustainable chromatography solution for drug discovery efforts.
