in a sample containing 5 mg organic compound, MW~200, dissolved in 1g DMSO-d 6 containing 100 ppm D 2O. The problem becomes worse as the molecular weight of the analyte increases. Solution Water (as H 2O, HDO or D 2O) can be minimized by adding molecular sieves to the solvent, agitating the mixtureand allowing it to stand for a few hours.

Organic Solvent with various Properties. DMSO is short for dimethyl sulfoxide, an organic sulfur compound with a wide range of different features. DMSO is a low-viscosity, high-boiling liquid (boiling point 189 °C, 372 °F) and an extremely versatile solvent, which has a characteristic odor and freezes at a temperature of +18 °C (64.4 °F.

Dimethyl sulfoxide (DMSO) is an important aprotic solvent that can solubilize a wide variety of otherwise poorly soluble polar and nonpolar molecules. This, coupled with its apparent low toxicity at concentrations <10%, has led to its ubiquitous use and widespread application.

Notes on NMR Solvents I. Introduction Most NMR spectra are recorded for compounds dissolved in a solvent. Therefore, signals will be observed for the solvent and this must be accounted for in solving spectral problems. To avoid spectra dominated by the solvent signal, most 1 H NMR spectra are recorded in a deuterated solvent. However.

Values for relative polarity, eluant strength, threshold limits and vapor pressure have been extracted from: Christian Reichardt, Solvents and Solvent Effects in Organic Chemistry, Wiley-VCH Publishers, 3rd ed., 2003.

DMSO’s (Dimethyl Sulfoxide) Properties and Potentials. DMSO is produced by oxygenating dimethyl sulfide, a by-product of wood pulp processing. It was discovered by Russian scientist Alexander Zaytsev in 1866 and was considered useful as a solvent.
