The use of CRMs for the NMR quantification of phosphorylated organic compounds and metabolites offers several advantages as it is based on a signal comparison of the analyte with an internal or external reference standard.
Reference or download our NMR shifts charts for the most common deuterated solvents. Proton NMR and carbon NMR tables aid chemists in separating signals of impurities that might originate from residual solvents or a reaction apparatus.
Presenting an article about the selective protonation of methyl groups in highly deuterated proteins. In which the structural NMR studies of small proteins, a maximum number of proton chemical shifts are usually assigned and NOEs connecting large numbers of sites
In certain cases, 1H qNMR reaches its limits, especially regarding the certification of complex and larger molecules. However, new fields of application often also bring along the presence of heteroatoms, namely 31P and 19F. We therefore introduced 3 CRMs for
