A convenient guide to help select replacement solvents for dichloromethane in chromatography

One of the largest contributors to chlorinated solvent waste in medicinal chemistry is chromatography. A set of “drug-like” compounds was employed to compare the relative eluting strengths of greener solvent systems. Disclosed herein is an experimentally-derived solvent selection guide to aid chemists in choosing greener solvents for chromatographic purification, with a particular focus on reducing dichloromethane usage.
