Deuterated chloroform, also known as chloroform-d, is the organic compound with the formula CDCl 3. Deuterated chloroform is a common solvent used in NMR spectroscopy. [2] The properties of CDCl 3 and ordinary CHCl 3 are virtually identical. Deuterochloroform was first made in 1935 during the years of research on deuterium. [3]
Deuterated solvents are a group of compounds where one or more hydrogen atoms are substituted by deuterium atoms. These isotopologues of common solvents are often used in nuclear magnetic resonance spectroscopy .

Chloroform, [10] or trichloromethane (often abbreviated as TCM), is an organochloride with the formula C H Cl 3 and a common solvent. It is a volatile , colorless, sweet-smelling, dense liquid produced on a large scale as a precursor to refrigerants and PTFE . [ 11 ]
Sodium deuteroxide or deuterated sodium hydroxide is a chemical compound with the formula Na O D or NaO 2 H. IUPAC recommends that the symbol for deuterium should be 2 H, [2] although most chemists use the term NaOD. It is a white solid very similar to sodium hydroxide, of which it is an isotopologue.
Deuterated dichloromethane (CD 2 Cl 2 or C 2 H 2 Cl 2) [a] is a form (isotopologue) of dichloromethane (DCM, CH 2 Cl 2) in which the hydrogen atoms (H) are deuterium (heavy hydrogen) (2 H or D). [2] Deuterated DCM is not a common solvent used in NMR spectroscopy as it is expensive compared to deuterated chloroform .
The output of these processes is a mixture of chloromethane, dichloromethane, chloroform, and carbon tetrachloride as well as hydrogen chloride as a byproduct. These compounds are separated by distillation .
