What is Carbohydrazide ?
Carbohydrazide CAS 497-18-7 is white crystalline powder, easily soluble in water, insoluble in alcohol, ether, benzene. Carbohydrazide decomposes on heating or exposure to uv to form ammonia, hydrogen, and nitrogen, which may be explosive with a blue flame when catalyzed by metal oxides and some metals such as platinum or raney nickel. A number of carbazides are known where one or more N-H groups are replaced by other substituents. They occur widely in the drugs, herbicides, plant growth regulators, and dyestuffs. Heating carbohydrazide may result in an explosion. Carbohydrazide is harmful if swallowed, irritating to eyes, respiratory system, and skin. Carbohydrazide is toxic to aquatic organisms.

Application of Carbohydrazide
A: Industrial grade
1) Oxygen scrubber: carbohydrazide is used to remove oxygen in boiler systems. Oxygen scrubbers prevent corrosion.
2) Precursor to polymers: carbohydrazide can be used as a curing agent for epoxide-type resins
3) Photography: carbohyrazide is used in the silver halide diffusion process as one of the toners. Carbohydrazide is used to stabilize color developers that produce images of the azo-methine and azine classes
4)Carbohydrazide has been used to develop ammunition propellants, stabilize soaps, and used a reagent in organic synthesis.
B: Pharmaceutical grade: Carbohydrazide is widely used in medicine area.
C: Agricultural grade: Carbohydrazide can also be used as Herbicides, and plant growth regulator.
