Dimethyl Sulfoxide (DMSO)

CAS : 67-68-5

HS Code : 2930300000

Packing : 220kg/drum

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 contact with the 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.

Application

1. Used for aromatic extraction, resin and dye reaction medium, acrylic polymerization and solvent extraction.
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

Function

1.DMSO is colorless, odorless and transparent liquid at room temperature.
2.DMSO is a kind of moisture absorption combustible liquid.
3.DMSO has characteristics of high polarity, high boiling point, non-proton, mixed with water, low toxicity and good heat
stability.
4.DMSO is soluble in ethanol, propanol,and many organic matters. It was known as"Omnipotent Solvent"

It has high selective extraction ability, used as polymerization and condensation solvent of acrylic resin and polysulfone resin, polymerization spinning solvent of polyacrylonitrile and cellulose acetate, extraction solvent for the separation of alkanes and aromatics. Aromatics, butadiene extraction, acrylic fiber spinning, plastic solvents, organic synthetic dyes, pharmaceuticals and other industries as reaction media. In medicine, it has anti-inflammatory and analgesic effects and has strong penetration into the skin.
