Dimethylsulfoxide (DMSO for short) is a sulfur-containing organic compound, English Dimethylsulfoxide, molecular formula (CH3) 2SO, at room temperature is colorless odorless transparent liquid, with hypersonic flammable liquid, both high polarity, high boiling point, aprotic, water mismissibility characteristics, very low toxicity, good thermal stability, It is not mixed with alkanes, and can dissolve in water, ethanol, propanol, ether, benzene and chloroform and other most organic matter, known as “universal solvent”. Dimethyl sulfoxide is one of the most powerful organic solvents in common use. It can dissolve most organic matter, including carbohydrates, polymers, peptides, and many inorganic salts and gases. It can dissolve solutes equal to 50-60% of its weight (other common solvents can only dissolve 10-20%), so it is important in sample management and high-speed drug screening. Under certain conditions, an explosive reaction occurs when dimethyl sulfoxide comes into contact with an acyl chloride. Dimethyl sulfoxide is widely used as a…
