VerwendenCarbohydrazide 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.
