Deuterated DMSO

Chemical structure of deuterated DMSO

Deuterated DMSO ((CD₃)₂S=O) is a form (called an isotopologue) of dimethyl sulfoxide (DMSO, (CH₃)₂S=O)) in which the hydrogen atoms ("H") are replaced with deuterium (heavy hydrogen) isotope ("D"). Deuterated DMSO is a common solvent used in NMR spectroscopy.
