Product Advantage
DMSO is known as a “universal solvent” due to its exceptional dissolving capability, which is specifically demonstrated as follows:
1. It is miscible with water, ethanol, acetone, ether, benzene, chloroform, and most organic substances. Except for petroleum ether, it can dissolve most common organic solvents.
2. At 20°C, it can absorb 30% (by weight) of hydrogen chloride, 30% (by weight) of nitrogen dioxide, and 65% (by weight) of sulfur dioxide.
3. It has extremely strong solvency, capable of dissolving solutes equivalent to 50–60% of its own weight, whereas most common solvents typically dissolve only 10–20%.
4. It has a relatively high dielectric constant (41.9 at 55°C), enabling it to effectively dissolve polar compounds and inorganic salts, while also dissolving many nonpolar compounds. This dual solvency is very rare among organic solvents.

Product Uses
Dimethyl sulfoxide can be used as organic solvent, reaction medium and intermediate of organic synthesis. Extremely versatile.
Dimethyl sulfoxide has high selective extraction ability, used as acrylic resin and polysulfone resin polymerization and condensation solvent, polyacrylonitrile and acetic acid fiber polymerization drawing solvent, alkane and aromatics separation extraction solvent, used in aromatics, butadiene extraction, acrylic fiber spinning, plastic solvent and organic synthetic dyes, pharmaceutical and other industries reaction medium.
In medicine, dimethyl sulfoxide has anti-inflammatory and analgesic effects, and has strong permeability to the skin, so it can dissolve some drugs, so that such drugs can penetrate into the human body to achieve therapeutic purposes.
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 sulphoxide can also be used as a dyeing solvent, stain remover and dyeing carrier of 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.
FAQ
How can dimethyl sulfoxide be classified based on its application fields, and what differences exist between the various grades?
Dimethyl sulfoxide can be divided into industrial grade dimethyl sulfoxide, pharmaceutical grade dimethyl sulfoxide and agricultural grade dimethyl sulfoxide according to its application fields and uses, and different grades of dimethyl sulfoxide may have differences in purity, purity and quality standards.
What are the pharmacological effects and mechanisms of action of dimethyl sulfoxide in medical applications?
Dimethyl sulfoxide can improve the metabolism of the affected area, and can play an anti-edema role to a certain extent. In addition, the local analgesic effect of dimethyl sulfoxide is because it can slow down the conduction rate of peripheral nerves, through such a mechanism to obtain the analgesic effect.,maintain health and prevent disease.
