Manufacturer Good Price Dimethyl Sulfoxide (DMSO) CAS 67-68-5
description
It is one of the most commonly used organic solvents with the strongest solubility. It can dissolve most organic matter, including carbohydrates, polymers, peptides, and many inorganic salts and gases. It can dissolve 50-60% of its own weight of solute (other general solvents can only dissolve 10-20%), so it is very important in sample management and high-speed drug screening. Under certain conditions, an explosive reaction can occur when Dimethyl sulfoxide comes into contact with the acid chloride. Dimethyl sulfoxide is widely used as solvent and reagent, especially as processing solvent and spinning solvent in acrylonitrile polymerization, as polyurethane synthesis and spinning solvent, as polyamide, polyimide and polysulfone resin synthesis Solvents, Chemicalbook and aromatic hydrocarbons, butadiene extraction solvents and solvents for the synthesis of chlorofluoroaniline, etc. In addition, in the pharmaceutical industry, dimethyl sulfoxide is also directly used as the raw material and carrier of some drugs. Dimethyl sulfoxide itself has anti-inflammatory and pain-relieving, diuretic, sedative and other effects, also known as "panacea", and is often added to drugs as an active component of pain-relieving drugs. Has the special property of permeating the skin very easily, resulting in an oyster-like taste to the user. Sodium cyanide in dimethyl sulfoxide can cause cyanide poisoning through skin contact. And dimethyl sulfoxide itself is less toxic. Dimethyl sulfoxide is used as an extractant by the majority of chemical and pharmaceutical companies. However, due to the high boiling point of DMSO, the operating temperature is too high, which leads to coking of materials, which affects the recovery of dimethyl sulfoxide and equipment cleaning. Increase energy consumption. Therefore, the recovery of DMSO has become a bottleneck for its further widespread use as an extractant. Dimethyl sulfoxide is a common aprotic organic solvent used to dissolve polar and nonpolar compounds. The deuterated form, DMSO-d6 (D479382), used primarily for NMR studies, is easily identifiable by its NMR spectrum because of its ability to dissolve most analytes.

Applications of DMSO
1. DMSO is used for aromatic hydrocarbon extraction, reaction medium for resin and dye, acrylic fiber polymerization, and solvent for spinning, etc.
2. DMSO can be used as organic solvent, reaction medium and organic synthesis intermediate. Very versatile. This product has high selective extraction ability, used as the polymerization and condensation solvent of acrylic resin and polysulfone resin, the polymerization and spinning solvent of polyacrylonitrile and acetate fiber, the extraction solvent of alkane and aromatic hydrocarbon separation. Aromatic hydrocarbon, butadiene extraction, acrylic fiber spinning, plastic solvent and reaction medium for organic synthetic dyes, pharmaceuticals and other industries. In terms of medicine, dimethyl sulfoxide has anti-inflammatory and analgesic effects, and has strong penetrating power to the skin, so it can dissolve certain drugs in Chemicalbook, so that such drugs can penetrate into the human body to achieve the purpose of treatment. Utilizing this carrier property of dimethyl sulfoxide, it can also be used as an additive for pesticides. A small amount of dimethyl sulfoxide is added to some pesticides to help the pesticide penetrate into the plant to improve the efficacy. Dimethyl sulfoxide can also be used as dyeing solvent, de-staining agent, dyeing carrier for synthetic fibers, absorbent for recovering acetylene and sulfur dioxide, synthetic fiber modifier, antifreeze, capacitor medium, brake oil, extraction of rare metals agent, etc.
3.DMSO can be used as analytical reagent and fixed liquid for gas chromatography, and also used as a solvent in ultraviolet spectrum analysis.
4.DMSO organic solvent, reaction medium and organic synthesis intermediate. Very versatile. With high selective extraction ability, it is used as the polymerization and condensation solvent of acrylic resin and polysulfone resin, the polymerization and spinning solvent of polyacrylonitrile and acetate fiber Chemicalbook, the extraction solvent of alkane and aromatic hydrocarbon separation, used for aromatic hydrocarbon , Butadiene extraction, acrylic fiber spinning, plastic solvent and organic synthetic dyes, pharmaceutical and other industrial reaction medium. In terms of medicine, it has anti-inflammatory and analgesic effects, and has strong penetration into the skin.
