Manufacturer Good Price Dimethyl Sulfoxide (DMSO) CAS 67-68-5

Dimethyl sulfoxide (referred to as DMSO) is a sulfur-containing organic compound, the English Dimethylsulfoxide, the molecular formula is (CH3) 2SO, is a colorless, odorless and transparent liquid at room temperature, a hygroscopic flammable liquid, and has both high polarity. , high boiling point, aprotic, miscible with water, extremely low toxicity, good thermal stability, immiscible with alkanes, soluble in most organic substances such as water, ethanol, propanol, ether, benzene and chloroform, known as For the "universal solvent". 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.
