AMMONIUM HYDROXIDE 28% NH3 IN WATER >=99.99% METALS BASIS (C005B-015404)

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.

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.
