Deuterated dichloromethane

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

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