WebMar 29, 2024 · Organic Chemistry. CDCl3 is a common solvent used for NMR analysis. It is used because most compounds will dissolve in it, it is volatile and therefore easy to get rid of, and it is non-reactive and will not exchange its deuterium with protons in the molecule being studied. It is also “silent” in the NMR and will not show peaks to interfere ...
