Descripción

Application

Hydrazinium hydroxide (N₂H₄.H₂O) can be used as a reducing agent to synthesize:

• Magnetic nickel nanoparticles by polyol process using nickel acetate as a precursor.
• Cu@Cu₂O core-shell nanoparticles via a chemical reduction method using CuSO₄.5H₂O as a precursor.

It can also be used as a reactant to prepare:
2H-indazolo[2,1-b]phthalazine-1,6,11(13H)-trione derivatives by Ce(SO₄)₂·4H₂O catalyzed condensation reaction with phthalic anhydride, aromatic aldehydes, and dimedone.
