I totally agree with the views expressed by Dr. Guerra,K., and Dr. Kaufman.,T.S., Chloroform gets stabilized ... 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 … 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 stored in brown-tinted bottles, often over copper chips or silver foil as stabilizer. … See more

WebJan 14, 2024 · Deuterated chloroform (CDCl3), also known as chloroform-d, is an isotopically enriched form of chloroform (CHCl3) in which most its hydrogen atoms consist of the heavier nuclide deuterium (heavy hydrogen) (D = 2H) rather than the natural isotopic mixture in which protium (1H) is predominant. WebChloroform-d (Deuterochloroform, CDCl 3), deuterated chloroform, is a standard purity solvent for NMR (Nuclear Magnetic Resonance) analyses.It is widely employed in high …
