13 C NMR Spectrum of DMSO-d 6. Pure deuterated DMSO shows no peaks in 1 H NMR spectroscopy and as a result is commonly used as an NMR solvent. [2] However commercially available samples are not 100% pure and a residual DMSO-d 5 1 H NMR signal is observed at 2.50ppm (quintet, J HD =1.9Hz).
The handling of this chemical may incur notable safety precautions. It is highly recommend that you seek the Material Safety Datasheet ( MSDS ) for this chemical from a reliable source such as SIRI , and follow its directions.
Dimethyl sulfoxide (DMSO) is an organosulfur compound with the formula (CH 3) 2 S O.This colorless liquid is the sulfoxide most widely used commercially. It is an important polar aprotic solvent that dissolves both polar and nonpolar compounds and is miscible in a wide range of organic solvents as well as water.
Samples were prepared by dissolution in deuterated chloroform (CDCl 3), deuterium oxide (D 2 O), or deuterated dimethylsulfoxide (DMSO-d 6). [5] Each spectrum is accompanied by a list of peaks with their respective intensities and chemical shifts reported in ppm and in Hz. Most spectra show the peak assignment.
Being a polar solvent with a high dielectric constants, dmso dissolves many metal salts to give the corresponding complexes. Other ligand-solvent combinations include acetonitrile and water, which respectively form metal-acetonitrile complexes and metal aquo complexes. Treatment of thioether complexes with peroxide reagents gives sulfoxide ...
USA TODAY's music critic saw plenty of amazing concerts in 2024 including Olivia Rodrigo and The Eagles at the Sphere. Here are her top 10, ranked.
cis-RuCl 2 (dmso) 4, a representative metal complex of a sulfoxide. Three DMSO ligands are S-bonded to Ru, one is O-bonded. Sulfoxides, especially DMSO, form coordination complexes with transition metals. Depending on the hard-soft properties of the metal, the sulfoxide binds through either the sulfur or the oxygen atom. The latter is ...
