General description

Crystals of hydrazine monohydrate exhibit triclinic crystal system and space group P3121.

Application

Hydrazine monohydrate has been used to synthesize 2-(6-ethylamino-3-ethylimino-2,7-dimethyl-3H-xanthen-9-yl)benzoic acid hydrazide and vinyl-benzylamine hydrochloride. It may also be used as a source of hydrogen via decomposition in the presence of supported bimetallic catalyst composed of Ni-Pt alloy nanoparticles and mesoporous CeO2 support.
Hydrazine monohydrate may be used as a reducing agent for the reduction of:
  • Nitroarenes in the presence of hydrogen peroxide functionalized carbon nanotubes.
  • 4-Iodo-3-nitroanisole to form 2-iodo-5-methoxyaniline.
  • Graphene oxide (GO) to form graphene.
