General description

Dimethyl sulfoxide-d6 (DMSO-d6) 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 CD3 radicals. Quantum yields of CD3 have been evaluated by infrared diode laser absorption spectroscopy. 100% DMSO-d6 has been used as solvent in the long-range COSY (Correlation Spectroscopy) experiment.

Application

Dimethyl sulfoxide-d6 has been used as solvent for the dissolution of glucan during its proton, 13C (Carbon-13) and 2D NMR (Two-Dimensional Nuclear Magnetic Resonance) spectral studies. Dimethyl sulfoxide-d6 may be used as a solvent to study the nuclear magnetic resonance spectra(NMR) of the corresponding 1,3- benzoxazines and 1,3-benzoxazinones, which tend to possess antimicrobial activity.
