Method development in quantitative NMR towards metrologically traceable organic certified reference materials used as (31)P qNMR standards

Quantitative nuclear magnetic resonance (qNMR) spectroscopy is employed by an increasing number of analytical and industrial laboratories for the assignment of content and quantitative determination of impurities. Within the last few years, it was demonstrated that (1)H qNMR can be performed with hi...
