Development of GSK's NMR guides – a tool to encourage the use of more sustainable solvents

Abstract

Residual solvents often appear as nuisance signals in experimental NMR spectra, and many chemists turn to well-known literature sources to quickly identify such peaks. While these publications are very useful, they do not currently include many solvents exemplified in green chemistry-related literature. This work provides a single compiled reference for NMR chemical shifts of 80 solvents in each of 6 deuterated NMR solvents. The overall green chemistry assessments, as reached via the methodology of the GSK Solvent Sustainability Guide, are displayed on these charts.
