WebDeuterated chloroform(CDCl3), also known as chloroform-d, is an isotopically enrichedform of chloroform(CHCl3) in which most of its hydrogenatoms consist of the heavier nuclidedeuterium(heavy hydrogen) (D = 2H) rather than the natural isotopicmixture in which protium(1H) is predominant. WebDeuterated chloroform is an isotopologue of chloroform with a single deuterium atom. CDCl 3 is a common solvent used in NMR spectroscopy.
