DMSO liquid 99.9%min Dimethyl Sulfoxide

 Dimethyl sulfoxide (DMSO for short) is a sulfur-containing organic compound, English Dimethylsulfoxide, molecular formula (CH3) 2SO, colorless and odorless transparent liquid at room temperature, hygroscopic flammable liquid, both high polarity , High boiling point, non-proton, miscible in water, very low toxicity, good thermal stability, not mixed with alkanes, soluble in water, ethanol, propanol, ether, benzene, chloroform and most other organic substances, known as As the "universal solvent". It is the one with the strongest dissolving power among the commonly used organic solvents. It can dissolve most organic substances, including carbohydrates, polymers, peptides, and many inorganic salts and gases. It can dissolve 50-60% of its own weight (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 occurs when dimethyl sulfoxide is in contact with acid chloride. Dimethyl sulfoxide is widely used as a solvent and reaction reagent, especially as a processing solvent and spinning solvent in the Chemicalbook reaction of acrylonitrile polymerization, as a polyurethane synthesis and spinning solvent, as a polyamide, polyimide and polysulfone resin Synthetic solvents, as well as aromatics, butadiene extraction solvents and synthetic chlorofluoroaniline solvents, etc. In addition, dimethyl sulfoxide is also directly used as the raw material and carrier of certain drugs in the pharmaceutical industry. Dimethyl sulfoxide itself has anti-inflammatory, analgesic, diuretic, sedative and other effects. It is also known as the "panacea" and is often added to medicines as the active component of analgesics. It has the special property of easily penetrating the skin, causing the user to feel a taste similar to oysters. The dimethyl sulfoxide solution of sodium cyanide can cause cyanide poisoning through skin contact. The 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, causing material coking, which affects the recovery of dimethyl sulfoxide and equipment cleaning. Increase energy consumption. Therefore, the recovery of dimethyl sulfoxide has become a bottleneck for its further use as an extractant.
