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 , known as It is Universal Chemicalbook 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.
