Dimethyl sulfoxide (DMSO) is a kind of sulfur-containing organic compound, the molecular formula is C2H6OS, at room temperature is colorless odorless transparent liquid, is a kind of hygrometric flammable liquid. With high polarity, high boiling point, good thermal stability, aprotic, and water miscible characteristics, can dissolve in ethanol, propanol, benzene and chloroform and other most organic matter, known as the "universal solvent".
In the presence of acid heating will produce a small amount of methyl mercaptan, formaldehyde, dimethyl sulfur, mesylate and other compounds. Decomposition phenomenon at high temperature, chlorine can occur violent reaction, burning in the air emit light blue flame. It can be used as organic solvent, reaction medium and intermediate of organic synthesis. It can also be used as a dyeing solvent, dye removal agent, dyeing carrier and absorption agent for recovering acetylene and sulfur dioxide of synthetic fibers.
Storage and packaging: Stored in a cool and dry place with ventilation and can be sealed for 12 months.
2. Organic solvents, reactive media and organic synthesis intermediates.
3. Used as analytical reagent and gas chromatographic stationary liquid, and also used as solvent during uv spectrum analysis.
4. Transdermal accelerator.
5. Antifreeze
