Deuterated dichloromethane (CD₂Cl₂ or C²H₂Cl₂)^[a] is a form (isotopologue) of dichloromethane (DCM, CH₂Cl₂) in which the hydrogen atoms (H) are deuterium (heavy hydrogen) (²H or D).^[2] Deuterated DCM is not a common solvent used in NMR spectroscopy as it is expensive compared to deuterated chloroform.

Notes

^ IUPAC recommends that the symbol for deuterium should be ²H, rather than D.^[1] It follows that the latter formula, C²H₂Cl₂, is more correct.
