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].
