Deuterated dimethyl sulfoxide (DMSO-D6) is an organic solvent with the formula (CD3)2SO. It is used to dissolve a wide range of organic compounds and is widely used within the pharmaceutical industry. It has a density of 1.19 g/cm3 (20 oC)
The 1H-NMR spectrum of deuterated dimethyl sulfoxide comprises of a quintet (e.g., 5 lines) at 2.50 ppm and a H2O/HDO resonance that generally appears at 3.3 ppm. The 13C-NMR spectrum gives rise to a septet (e.g., 7 lines) at 39.1 ppm (vs. TMS).
Cambridge Isotope Laboratories (CIL) is pleased to offer highly enriched and pure deuterated dimethyl sulfoxide for use with high-field, NMR spectroscopy These products are carefully manufactured and packaged so that the introduction of any impurity, including paramagnetic impurities, such as dissolved O2(g), into the product is minimized.
DMSO-d6 is highly hygroscopic and thus care should be taken to minimize contact of the solvent with atmospheric water.
