[Question from NMRWiki Q&A forum] About paragnetic impurities, inorganic salts, bad workups, etc. and their impact on small-molecule NMR spectra
About paragnetic impurities, inorganic salts, bad workups, etc. and their impact on small-molecule NMR spectra
I sometimes face the challenge of explaining to my organic chemists that, even if no impurity signals are visible in their 1H spectrum, other signs (like FID shape, very poor s/n compared to what could be expected with the sample qty, broad peaks, bad resolution...) indicate that clearly, something is wrong with their sample.
Everybody would agree that it's way much easier to convince an invidual based on concrete facts ("look, here we can see solvent/starting material/side...

Two-dimensional concurrent HMQC-COSY as an approach for small molecule chemical shift assignment and compound identification
Two-dimensional concurrent HMQC-COSY as an approach for small molecule chemical shift assignment and compound identification
Abstract Chemical shift assignment is the first step toward the structure elucidation of natural products and other chemical compounds. We propose here the use of 2D concurrent HMQC-COSY as an experiment for rapid chemical shift assignment of small molecules. This experiment provides well-dispersed 1Hâ??13C peak patterns that are distinctive for different functional groups plus 1Hâ??1H COSY connectivities that serve to identify adjacent groups. The COSY diagonal...

MDM2 is a regulator of cell growth processes that acts by binding to the tumor suppressor protein p53 and ultimately restraining its activity. While inactivation of p53 by mutation is commonly observed in human cancers, a substantial percentage of tumors express wild type p53. In many of...
