The main uses of dimethyl sulfate

Dimethyl sulfate (DMS) is a chemical reagent that is irritating, corrosive, toxic, and carcinogenic, and has been used as a chemical weapon. However, its boiling point is relatively high, reaching over 180 degrees, and compared to iodomethane, DMS still has a certain level of safety.

Common protective reagent - dimethyl sulfate

Dimethyl sulfate is an excellent methylation reagent that can be used as a methylation reagent for phenols, amines, and thiols. The transfer of methyl groups is through the Sn2 reaction, and the transfer of one methyl group is easier than the second one. Due to its high toxicity
