Description of Dimethyl sulfoxide

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 melting 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.

What is Dimethyl sulfoxide?

With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Dimethyl sulfoxide which has developed particularly rapidly in recent years. Do you know about Dimethyl sulfoxide?
The official answer: Dimethyl sulfoxide (DMSO) is a sulfur-containing organic compound with the molecular formula C2H6OS, a colorless and odorless transparent liquid at room temperature, and a hygroscopic flammable liquid. It has the characteristics of high polarity, high boiling point, good thermal stability, non-protonic, miscible with water, soluble in most organic substances such as ethanol, propanol, benzene, and chloroform, etc. It is known as a “universal solvent”. When heated in the presence of an acid, a small amount of methyl mercaptan, formaldehyde, dimethyl sulfide, methanesulfonic acid, and other compounds will be produced. It decomposes at high temperatures, reacts violently with chlorine, and burns in air with a light blue flame. It can be used as an organic solvent, reaction medium, and organic synthesis intermediate. It can also be used as dyeing solvent of synthetic fiber, dyeing agent, dyeing carrier, and absorbent of recovering acetylene and sulfur dioxide.

What’s the application of Dimethyl sulfoxide?

DMSO is widely used as solvents and reaction reagents, especially in acrylonitrile polymerization reactions as processing solvents and drawing solvents, in polyurethane synthesis and drawing solvents, in polyamide, polyimide and polysulfone resin synthesis solvents, as well as aromatics, butadiene extraction solvents, and synthesis solvents for chlorofluoroaniline.

DMSO is dimethyl sulfoxide, which is widely used. It is used as a solvent for acetylene, aromatics, sulfur dioxide, and other gases as well as a solvent for spinning acrylic fiber. It is an extremely important nonprotonic polar solvent that is soluble in water and organic solvents. It has strong permeability to the skin and helps the penetration of drugs into the body. It can also be used as an additive for pesticides. It is also a very important chemical reagent.

DMSO is also an osmoprotective agent that lowers the cell freezing point, reduces the formation of ice crystals, mitigates free radical damage to cells, and alters the permeability of biological membranes to electrolytes, drugs, toxicants, and metabolites.

Methyl sulfoxide is an extremely important nonprotonic polar solvent that is soluble in both water and organic solvents. It is widely used as a solvent and reaction reagent with a high selective extraction capacity. Dimethyl Sulfoxide itself has anti-inflammatory and analgesic, diuretic, and sedative effects, and can be used directly as raw material and carrier for certain drugs in the pharmaceutical industry. It is known as a “cure-all” and is often added to drugs as an active component of painkillers.

WHY THEY SAY TO US

Peter has been my partner for many years, we met at the Shanghai CPHI Fair in 2014, for the first time I didn't have much interest in Peter's products because our company had a stable supplier. Although we didn't work together, Peter would often send me important news and interesting trend information about the industry, so we became good friends, even though I didn't place any orders with him during this time, even if it was a sample order. In September 2016, our original supplier was unable to provide us with the quality and delivery guarantees we needed, so I first thought of Peter and his company. Until now, we have maintained a very good personal friendship in addition to a steady business relationship.

In all my years of sourcing from China, I first time to found that working with Sincere Chemical was so good, they helped me with all the production and delivery as well as a lot of technical expertise, which saved me a lot of time. When I first approached Peter for a quotation for Optical Brightener, he made me a detailed quotation with not only prices but also foreign trade details, company profile, company strengths, R&D capabilities, production capacity, packaging methods, raw material control, environmental protection, and much more. This information was a very important reference for me in making purchasing decisions. Sincere Chemical is a trustworthy supplier and I believe our business will grow from strength to strength!

Hi, I'm Kim, I'm Peter's partner and although I don't like him very much (because he never gives me more money for my prices, hahaha) I'm still willing to write him customer feedback. As an international buyer, I have to deal with a lot of things every day and my inbox is often full of development letters. It's a lot of junk and meaningless pleasantries, which I don't like that much, but Peter's emails always give me a better understanding of the product and the industry. I am also very pleased with his work ethic, and I am very happy with his work every time I work with him, not only in providing quotations but also in facilitating all the details of my work so that I can concentrate more on other things, so he is the best supplier for me. Although his prices are not the lowest among all suppliers, his products give me the greatest peace of mind.
