Description and Uses
First synthesized in 1866 by Alexander Zaytsev in the Russian Empire, dimethyl sulfoxide is an organosulfur compound. This colorless liquid 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.
Suitable for HPLC, spectrophotometry, environmental testing
