Gaylord announced expanded DMSO production capacity in Tuscaloosa, Alabama, which came on-line in 2010. [ 2 ] Prior to being a subsidiary of Temple-Inland , Gaylord Chemical was a division of Gaylord Container Corporation , the successor (1986–2002) of the brown paper division of Crown Zellerbach (1928–86).
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.
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 13 C chemical shift of DMSO-d 6 is 39.52ppm (septet ...
Dimethyl sulfone (DMSO 2) is an organosulfur compound with the formula (CH 3) 2 SO 2. It is also known by several other names including methyl sulfone and (especially in alternative medicine) methylsulfonylmethane (MSM). [4] This colorless solid features the sulfonyl functional group and is the simplest of the sulfones. It is relatively inert ...

Impure dimethyl sulfate was prepared in the early 19th century. [4] J. P. Claesson later extensively studied its preparation. [5] [6]It was investigated for possible use in chemical warfare in World War I [7] [8] in 75% to 25% mixture with methyl chlorosulfonate (CH 3 ClO 3 S) called "C-stoff" in Germany, or with chlorosulfonic acid called "Rationite" in France.
