On April 19, 2022, Peterson, Joshua W.; Burt, Scott R.; Yuan, Yu; Harper, James K. published an article.Quality Control of (Trimethoxymethyl)benzene The title of the article was Rapid, quantitative nuclear magnetic resonance test for oxygen-17 enrichment in water. And the article contained the following:
NMR (NMR) studies involving 17O are increasingly important in mol. biol., material science, and other disciplines. A large number of these studies employ H217O as a source of 17O, and this reliance can be limiting because the high cost of H217O. To overcome this constraint, a recent study proposed a distillation scheme capable of producing significant quantities of H217O at a low cost. Although this method is reported to be effective, the reactions proposed to quantify percent of 17O enrichment are either time intensive or have a risk of errors due to the isotope effect. Here, an alternative reaction scheme is described to measure 17O water that ultimately creates Me benzoate as the sole 17O-containing product. The proposed reaction is completed in a matter of minutes at room temperature, produces only one 17O product, and requires no clean-up step. The large isotope shift observed in solution NMR between the 13C=16O and 13C=17O resonances allows for integration of the individual peaks. This 13C NMR anal. is found to be highly accurate over a wide enrichment range and is accessible to most NMR spectroscopists. The experimental process involved the reaction of (Trimethoxymethyl)benzene(cas: 707-07-3).Quality Control of (Trimethoxymethyl)benzene
