Product Overview

Dimethyl Sulfoxide (DMSO) — also written dimethyl sulfoxide anhydrous, DMSO dimethyl sulfoxide, dimethylis sulfoxidum, and commonly abbreviated as DMSO — is a clear, colorless liquid with strong solvency and very high boiling point. It is a widely used polar aprotic solvent in pharmaceuticals, polymer processing, electronics cleaning, extraction and specialty chemical synthesis.
It is colorless liquid, and is hygroscopic. It is almost odorless with a bitter taste. It can be dissolved in water, ethanol, acetone, ether, benzene and chloroform.

Performance & Benefits

Excellent solvency for polymers, resins, active ingredients and specialty chemicals.
Low volatility and high boiling point for stable processing and formulation.
Broad miscibility with water and many organic solvents.
Useful as a carrier solvent in lab, pharmaceutical and industrial systems.


Typical Applications

Pharmaceuticals and life science: process solvent, formulation aid and penetration enhancer.
Polymer and resin processing: solvent for high-performance materials.
Electronics and precision cleaning: solvent for cleaning and formulation systems.
Extraction and specialty synthesis: strong solvent for difficult-to-dissolve compounds.

It can be used for the extraction of arene, also as the reaction medium used for resins and dyes, and applied to acrylic polymerization and spinning solvent.

It can be used as an organic solvent, reaction medium and the intermediates of organic synthesis. It is highly versatile. This product has a highly selective extraction capacity, and can be used as the polymerization and condensation solvent of acrylic resin and polysulfone resin, as the polymerization and spinning solvent of polyacrylonitrile and cellulose acetate, as the extraction solvent for separating alkanes and arenes, and as the reaction medium for the arenes, butadiene extraction, acrylic fiber, plastic solvents, organic and synthetic dyes, and pharmaceuticals industries. In the field of medicine, dimethyl sulfoxide has anti-inflammatory and analgesic effect with a strong capability of penetration through the skin, and thus being able to dissolve certain drugs and boost their penetration into the human body to achieve the therapeutic purposes. Taking this carrier property of dimethyl sulfoxide can make it be used as pesticide additives. Add a small amount of dimethyl sulfoxide in some pesticides can facilitate the penetration of pesticides into the plant in order to improve the efficacy. dimethyl sulfoxide can also be used as the dye solvent, dye removing agent, and dye carrier for the synthetic fibers. It can also be used as the absorbent of recycling acetylene and sulfur dioxide and also the modifiers of synthetic fiber, antifreeze agent and the capacitor dielectric, brake oil, and extractant of the rare metals.

It can be used as analytic solvents and fixing agent of gas chromatography as well as the solvent for analyzing UV spectra.
