General description

5-Methyl-4-nitroimidazole, an imidazole derivative, is a heterocyclic NH-acid. Its nitration in the presence of acetic anhydride/glacial acetic acid has been studied.

Application

5-Methyl-4-nitroimidazole may be used in the following:
  • To trap the reactive 1:1 intermediate formed during the reaction between triphenylphosphine and dibenzoylacetylene.
  • As a starting reagent in the synthesis of pyrazole derivatives.
  • Fabrication of zeolitic imidazolate frameworks (ZIFs).
