Description

Application

Diethyl sulfate can be used as a reactant for the synthesis of:

Biologically active compounds such as bispyrazole, pyrazolopyrimidine and pyridine containing antipyrinyl moieties.
N-substituted-2-styryl-4(3H)-quinazolinones.
Ionic liquids with pyrrolidinium, piperidinium and morpholinium cations, having potential applications as electrolytes.

It can also be used as an alkylating agent to synthesize 1-alkyl/aralkyl-2-(1-arylsufonylalkyl)benzimidazoles and an ionic liquid ethylmethylimidazole ethylsulfate ([EMIM][EtSO₄].
