Carbon-13 NMR for chloroform - Chemistry Stack Exchange

Deuterated chloroform, also known as chloroform-d, is the organic compound with the formula C HCl3 or CDCl3. Deuterated chloroform is a common solvent used in NMR spectroscopy. The properties of CDCl3 and ordinary CHCl3 (chloroform) are virtually identical. See more Deuterated chloroform is commercially available. It is more easily produced and less expensive than deuterated dichloromethane. Deuterochloroform is produced by the reaction of hexachloroacetone with … See more In proton NMR spectroscopy, deuterated solvent (enriched to >99% deuterium) is typically used to avoid recording a large interfering signal or signals from the proton(s) (i.e., … See more Chloroform reacts photochemically with oxygen to form chlorine, phosgene and hydrogen chloride. To slow this process and reduce the … See more WebThere are three reasons why deuterated solvents are used in NMR spectroscopy. Reason 1: To avoid swamping by the solvent signal. There is usually much more solvent than sample in an NMR tube. An ...
