Carbohydrazide
Alias:Hydrazine, 1,3-Diaminourea; Carbonic DihydrazideCas Number:497-18-7Molecular formula:CON4H6Molecular weight:90.09Properties:
Carbohydrazide is white crystal powder.Carbohydrazide is used as an oxygen scavenger for water boiler feed and heating systems to prevent corrosion damage. Carbohydrazide is used as a reducing agent for the recovery of precious metals. Carbohydrazide is used as a polymerization catalyst and a chain extender in urethane coatings. Carbohydrazide is used as an auxiliary in photographic industry to prevent discolouration. Carbohydrazide is used as an intermediate for pharmaceuticals, stabilizers and water treatment chemicals.
Carbohydrazide and its derivatives are versatile intermediates. They have active applications in organic synthesis for agrochemicals, pharmaceuticals, photographic, heat stabilizers, polymerization catalysts, flame- retardants, blowing agents for plastics, explosives, and dyes. Recently, hydrazine is applied to lcd (liquid crystal displays) as the fuel to make faster thin-film transistors.
