Application

Hydrazin hydrate (80% solution in water) can be used as a reducing agent for the reduction of exfoliated graphene oxide (GO), which is used for the preparation of GO nanocomposites. It is also used as a reagent in the synthesis of 3-amino-2-thiohydantoins by reacting with alkyl isothiocynatocarboxylates.
