Usage And Synthesis
Overview

Dimethyl sulfoxide (abbreviated DMSO) is a sulfur-containing organic compound; molecule formula: (CH3) 2SO; It exhibits as colorless, odorless, hygroscopic and flammable transparent liquid at room temperature. It has both high polarity as well as high-boiling point. It also has aprotic and water-miscible characteristics. It has low toxicity, good thermal stability, and is not miscible with paraffin. It is soluble in water, ethanol, propanol, ether, benzene and chloroforrm and many other kinds of organic substance and is called as the "universal solvent." It is a common organic solvent which has the strongest dissolving ability. It can dissolve most the organic compounds including carbohydrates, polymers, peptides, as well as many inorganic salts and gases. It can dissolve certain amount solute whose weight is equals to 50-60% of itself (other common solvents usually only dissolve 10-20%), so it is very important in the sample management as well as high-speed screening of drugs. Under certain conditions, contact between dimethyl sulfoxide and chloride can even lead to explosive reaction.
dimethyl sulfoxide is widely used as solvents and reagents, particularly as the processing reagent and spinning solvent at the reaction of acrylonitrilee polymerization used for polyurethane synthesis and the spinning solvent. It can also be used as the synthetic solvent for polyamide, polyimide and polysulfone resin as well as the extraction solvents for aromatic hydrocarbon and butadiene extraction solvents and solvents for synthesizing chlorofluoroaniline. In addition, dimethyl sulfoxide can also be directly used as the raw material or carrier of some drug in the pharmaceutical industry. dimethyl sulfoxide itself has various effects such as anti-inflammatory, analgesic, diuretic, and sedative, and thus also being known as "panacea" which is usually as the active ingredient of analgesic medication being added to the drug.
