Dimethyl sulfoxide, with the chemical formula (CH₃)₂SO and commonly abbreviated as DMSO, is a colorless, transparent organic liquid with a high boiling point and low melting point. It has excellent solubility, capable of dissolving a wide range of organic and inorganic substances, and possesses high polarity, making it an outstanding solvent and reaction medium in chemical processes. The sulfur atom in DMSO's molecular structure also gives it slight reducing properties, allowing it to act as a reducing agent in certain chemical reactions.
dimethyl sulfoxide uses
- Aromatics extraction, reaction medium of resin and dye, solvent of acrylic fiber polymerization and drawing, etc.
- Used as analytical reagent and gas chromatography stationary liquid, also used as solvent in ultraviolet spectrum analysis
- Dimethyl Sulfoxide solvent as organic solvent, reaction medium and organic synthesis intermediate. It is widely used. With high selective extraction ability, it can be used as polymerization and condensation solvent for acrylic resin and polysulfone resin, polymerization drawing solvent for Polyacrylonitrile and acetic acid fiber, extraction solvent for separation of alkane and aromatics, reaction medium for aromatics and butadiene extraction, acrylic fiber spinning, plastic solvent, organic synthetic dyes etc.
