Quantitative NMR (qNMR)
Explaining the internal standard method, external standard method, and considerations to keep in mind step by step!
The document includes the quantification of organic compounds and discusses internal and external standard methods. Quantitative NMR (qNMR) has become an efficient tool for quantifying organic compounds, and its use has been expanding in the pharmaceutical and chemical industries in recent years. Generally, proton NMR is used, but when considering the introduction of qNMR in new fields such as metabolomics, biomarker discovery, and physiological pathways, the presence of more complex molecules and systems makes the use of 1H-qNMR challenging. In such cases, using other NMR-active nuclei, namely 31P or 19F, may be a better option.
