Deuterated chloroform - Wikipedia
Deuterated chloroform, also known as chloroform- d, is the organic compound with the formula CDCl3. Deuterated chloroform is a common solvent used in NMR spectroscopy. [2] . The properties of CDCl3 and ordinary CHCl3 (chloroform) are virtually identical. Deuterochloroform was first made in 1935 during the years of research on deuterium. [3]
