| Dimethyl sulfoxide, DMSO, is an excellent internal standard for the analysis of many solvent mixtures by quantitative nuclear magnetic resonance, qNMR. DMSO is relatively nontoxic, has a lower volatility than many other common solvents, is sufficiently water soluble to be used with D2O as the NMR solvent, and exhibits a single peak in its 1-H spectrum. Solvent mixtures analyzed in this study include acetone, ethyl alcohol, methyl alcohol, tetrahydrofuran and N,N-dimethylformamide. The technique is simple, rapid, and gives good results at the per cent level. |
