It is a colourless liquid with an ammonia-like odor and it is derived from the same industrial chemical processes used to manufacture ammonia. However, hydrazine has physical properties that are more similar to those of water. Direct alkylation of hydrazines with alkyl halides in the presence of base affords alkyl-substituted hydrazines, but the reaction is typically inefficient due to poor control on level of substitution (same as in ordinary amines). The reduction of hydrazones to hydrazines presents a clean path for the production of 1,1-dialkylated hydrazines. Being bifunctional, with two amines, hydrazine is a key building block for the preparation of many heterocyclic compounds via condensation with a range of difunctional electrophiles. With 2,4-pentanedione, it condenses to give the 3,5-dimethylpyrazole. In the Einhorn-Brunner reaction, hydrazines react with imides to give triazoles. Hydrazine is a convenient reductant because the by-products are typically nitrogen gas and water. Thus, it is used as an antioxidant, an oxygen scavenger, and a corrosion inhibitor in water boilers and heating systems. It is also used to reduce metal salts and oxides to the pure metals in electroless nickel plating and plutonium extraction from nuclear reactor waste.AmerzineCatalyzed hydrazineDiamideDiamineDiazaneH2NNH2HDZHydrazinHydrazine (anhydrous)Hydrazine (hydrazine sulfate)Hydrazine (hydrazine sulphate)Hydrazine baseHydrazine solutionHydrazine sulfateHydrazine, anhydrousHydrazine/hydrazine sulfateHydrazinesHydrazynaLevoxineN2H4Nitrogen hydrideOxytreat 35Scav-ox IIUltra pureZeroxH4N232.045232.037448138hydrazinehydrazine302-01-2NNInChI=1S/H4N2/c1-2/h1-2H2OAKJQQAXSVQMHS-UHFFFAOYSA-N belongs to the class of inorganic compounds known as homogeneous other non-metal compounds.
