一般描述

Dimethyl sulfoxide (DMSO) is a polar solvent. DMSO activated by various electrophiles (oxalyl chloride) has been used to oxidize various alcohols (primary, secondary, allylic, benzylic, hindered and bicyclic). Carbonyl compounds are formed as reaction products. It has been proposed as an alternate solvent for methyl cellosolve for use in ninhydrin reaction, due to its high stability.

应用

Dimethyl sulfoxide (DMSO) has been used as a solvent in the high-throughput compound screening studies conducted on Mtb (Mycobacterium tuberculosis) H37Rv host cells.

注意

在室温下容易过冷并缓慢重融。 固化产品可以通过加热至室温来重新液化，而不会损害产品。
