Dimethylsulfoxide (DMSO for short) is a sulfur-containing organic compound with the English name Dimethylsulfoxide and the molecular formula of (CH3)2SO. It is a colorless and odorless transparent liquid at room temperature, a hygroscopic flammable liquid with high polarity, high boiling point, aprotic, miscible in water, extremely low toxicity, good thermal stability, immiscible with alkanes, and soluble in water, ethanol, propanol, diethyl ether, etc. It is the most soluble organic solvent in common use. It can dissolve most organic substances, including carbohydrates, polymers, peptides, and many inorganic salts and gases. It can dissolve 50-60% of its own 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, when dimethyl sulfoxide comes into contact with acyl chloride, an explosive reaction will occur.
Dimethyl sulfoxide is widely used as solvent and reaction reagent, especially as processing solvent and spinning solvent in acrylonitrile polymerization, polyurethane synthesis and spinning solvent, polyamide, polyimide and polysulfone resin synthesis solvent, aromatic hydrocarbon, butadiene extraction solvent and solvent for synthesizing chlorofluoroaniline. In addition, dimethyl sulfoxide is directly used as raw material and carrier of some drugs in pharmaceutical industry. Dimethyl sulfoxide itself has anti-inflammatory, analgesic, diuretic and sedative effects, and is also known as a "panacea", and is often added to drugs as an active component of analgesic drugs. It has the special property of easily penetrating the skin, which makes users feel like oysters. Dimethyl sulfoxide solution of sodium cyanide can cause cyanide poisoning through skin Chemicalbook contact. However, dimethyl sulfoxide itself is less toxic. Dimethyl sulfoxide (DMSO) is used as extractant in chemical and pharmaceutical enterprises. However, due to the high boiling point of DMSO, the operating temperature is too high, which causes coking of materials, affects the recovery of DMSO and equipment cleaning, and also increases energy consumption. Therefore, the recovery of dimethyl sulfoxide has become a bottleneck for its further use as an extractant. Dimethyl sulfoxide is a common aprotic organic solvent, which is used to dissolve polar and nonpolar compounds. The deuterated form DMSO-d6(D479382) is mainly used for nuclear magnetic resonance research, and its nuclear magnetic resonance spectrum is easy to identify because of its ability to dissolve most analytes.
