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]
