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 acidity of the solvent, chloroform-d is … See more WebThe NMR spectrometer will acquire data for the wrong chemical shift range and you will potentially not have any usable data when you open Spinworks. (The NMR spectrometer examines a ~12 ppm range based on the expected solent peak. If the wrong solvent is selected, the wrong 12 ppm range will be studied, which may or may not contain peaks …
