What is Carbohydrazide:

Carbohydrazide is used primarily as an oxygen scrubber in water treatment systems. It is added also to control corrosion. It is also used as a curing agent for epoxide-type resins, to stabilize soaps, as a reagent in organic synthesis, and to develop ammunition propellants. It is a safer alternative to hydrazine. Carbohydrazide reacts with oxygen at low temperatures and pressures, and the products of the reaction are volatile. Heating carbohydrazide may result in an explosion. Carbohydrazide, like hydrazine, will also passivate metal surfaces.


Carbohydrazide Exposure and Health Risks:

Carbohydrazide is an irritant capable of causing reactions to the skin, eyes, and respiratory tract. It can cause an allergic reaction when contacting skin. Carbohydrazide is toxic if swallowed. Carbohydrazide is also very toxic to aquatic organisms.



There are no listed regulations or restrictions for carbohydrazide levels in water.
