Raw Material Universal Solvent Organic Chemicals Dimethyl Sulfoxide DMSO CAS 67-68-5

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.

DMSO is a polar aprotic solvent used in chemical reactions such as the polymerase chain reaction (PCR) and can also be used as a cryoprotectant vitrification agent for the preservation of cells, tissues, and orga ns. DMSO can be used in cell freezing media to protect cells from mechanical damage caused by ice crystals.

Dimethyl sulfoxide (DMSO) is an organosulfur compound with the formula (CH3)2SO. 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. It has a relatively high boiling point. DMSO has the unusual property that many individuals perceive a garlic-like taste in the mouth after DMSO makes contact with their skin.

In terms of chemical structure, the molecule has idealized Cs symmetry. It has a trigonal pyramidal molecular geometry consistent with other three-coordinate S(IV) compounds, with a nonbonded electron pair on the approximately tetrahedral sulfur atom.

Used as an analytical reagent and gas chromatography fixed solution, also used as a solvent in ultraviolet spectrum analysis, but also used for aromatic extraction, resin and dye reaction medium, acrylic fiber polymerization, drawing solvent.Using this carrier property of dimethyl sulfoxide, it can also be used as an additive to pesticides. Adding a small amount of dimethyl sulfoxide to some pesticides helps the pesticide penetrate into the plant to improve its efficacy. Dimethyl sulfoxide can also be used as a dyeing solvent, destaining agent and dyeing carrier for synthetic fibers, and can also be used as an absorber for recovering acetylene and sulfur dioxide, synthetic fiber modifier, antifreeze, capacitive media, brake oil, rare metal extractor and so on.
