Sigma-Aldrich® Dimethyl sulfoxide-d6 "100%", 99.96 atom % D

Dimethyl sulfoxide-d 6 (DMSO-d 6 ) is a deuterated solvent. It is 100% isotopically enriched NMR (Nuclear Magnetic Resonance) solvent. It is widely employed in high resolution NMR studies due to its high chemical and isotopic purity. On photoirradiation in the range of 193 and 222nm, it undergoes decomposition to afford CD 3 radicals. Quantum yields of CD 3 have been evaluated by infrared diode laser absorption spectroscopy. 100% DMSO-d 6 has been used as solvent in the long-range COSY (Correlation Spectroscopy) experiment.
