General description

Dimethyl sulfoxide-d6 (DMSO-d6) is a deuterated NMR solvent containing 0.03% (v/v) TMS (tetramethylsilane). It is useful in NMR-based research and analyses. It undergoes photodissociation to generate CD3 radical photoproducts, which have been analyzed by infrared diode laser-absorption spectroscopy. Dissociation dynamics of DMSO-d6 at 193nm was examined using photo fragment translational spectroscopy method.

Application

Dimethyl sulfoxide-d6 (DMSO-d6) may be used as an NMR solvent for 1H and 13C NMR experiments.
