Beschreibung

Allgemeine Beschreibung

Dimethyl sulfoxide-d₆ (DMSO-d₆) is a deuterated solvent and it contains 1%(v/v) TMS (Tetramethylsilane, added as a stabilizer). 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 laserabsorption spectroscopy. 100% DMSO-d₆ has been used as solvent in the long-range COSY (Correlation Spectroscopy) experiment.

Anwendung

DMSO-d₆ along with glycerol or glycerol-d₈ forms highly viscous binary solvents with high dissolution power for complex biological active compounds.
