| Application: | Ammonium hydroxide solution (28% NH3 in H2O) can be used as: • A medium to prepare magnetite (Fe3O4) nanoparticles via a modified controlled chemical coprecipitation method using divalent or trivalent iron salts as iron precursors. • A reagent in ammonolysis. • A solvent to synthesize 1, 4 dihydropyridines via one-pot condensation of an aldehyde and alkyl acetoacetate. |
| General description: | Ammonium hydroxide solution is also called aqueous ammonia, aqua ammonia, or ammonia water. It is a weak base mainly used as a nitrogen source to prepare other nitrogen-containing organic and inorganic chemicals such as urea, ammonium carbonate, ammonium sulfate, etc. |
