• Uses: It is widely used in the production of pharmaceuticals, herbicides, plant growth regulators, dyes, etc.(1) carbohydrazide is a derivative of hydrazine with a strong reduction. It can be not only used as the intermediates for producing energy-containing materials, but also can be used directly as the components of explosives and propellants. (2) it can be used as the preservative of refinery equipment and can also be used as the oxygen scavenger of boiler water treatment agent (3) It can be used as the cross-linking agent of the elastic fiber in the field of chemical fiber industry (4) it can be used as the chemical raw materials and chemical industrial intermediates and is widely used in medicine, herbicides, plant growth regulators, dyes and other industries. It can be used as the component of the rocket propellant, the stabilizer of color development and soap quality, the antioxidants of rubber, the oxygen scavenger of boiler water, and the passivation agent of metal. Carbohydrazide is a derivative of hydrazine with a strong reduction. It can be used as the intermediate of producing energy-containing materials and also be used directly for the components of explosives and rocket propellant. It can also be used as the oxygen scavenger of boiler water and is the most advanced materials for scavenging oxygen of boiler water in the world today. It has low toxicity, high melting point and a deoxidation efficiency being far greater than the materials currently used. It is an ideal product for both safety and environmental protection. In addition, it can be used as the cross-linking agent of the elastic fiber in the field of chemical fiber industry. It can also be used as the chemical raw materials and chemical industrial intermediates and is widely used in medicine, herbicides, plant growth regulators, dyes and other industries. The above information is edited by the lookchem of Dai Xiongfeng. Organic intermediate and photographic chemical. Carbohydrazide is widely utilized as a curing agent for epoxide-type resins and as an oxygen scrubber in boiler systems. It is applied in photography to stabilize color developers that produce images of the azo-methine and azine classes. It is used to develop ammunition propellants and stabilize soaps. It is also a useful reagent in organic synthesis.
