Description and Uses
Hydrazine Hydrate used as a reactant in the cyclizations of pyridinones. It is also used in the study of nanocrystal semiconductors, participating in the functionalization and passivation of surface states. It is widely used as a reducing agent or an intermediate of synthesis in various industrial sectors like water treatment (effluents, industrial boilers), chemical treatment process (metals, mine extraction) or active ingredients synthesis (pharmaceuticals and agrochemicals).
