Carbohydrazide is the chemical compound with the formula OC(N2H3)2. It appears as a white solid that is soluble in water, but not in many organic solvents, such as ethanol, ether or benzene. It decomposes upon melting. 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.

==Production== Industrially the compound is produced by treatment of urea with hydrazine: OC(NH2)2 + 2 N2H4 → OC(N2H3)2 + 2 NH3 It can also be prepared by reactions of other C1-precursors with hydrazine, such as carbonate esters. It can be prepared from phosgene, but this route cogenerates the hydrazinium salt [N2H5]Cl and results in some diformylation. Carbazic acid is also a suitable precursor: N2NH3CO2H + N2H4 → OC(N2H3)2 + H2O
