    General description

    Ammonium hydroxide is a weak base mainly used as a source to prepare other ammonium compounds like urea, ammonium carbonate and ammonium sulfate etc.[4]

    Application

    Ammonium hydroxide solution may be used:
    • As a medium to prepare magnetite (Fe3O4) nanoparticles via a modified controlled chemical coprecipitation method.[5]
    • As a solvent and reagent to prepare 4-aryl and 4-alkyl-2,6-dimethyl-1,4-dihydro-3,5-pyridinedicarboxylates via Hantzsch synthesis in a microwave cavity synthesizer.[6]
