Carbohydrazide is the chemical compound with the formula OC(N 2 H 3) 2. It appears as a white solid that is soluble in water, [ 1 ] [ 2 ] but not in many organic solvents, such as ethanol, ether or benzene.
In chemistry, a carbazide is a functional group with the general formula RNH-NH(C=O)NH-NHR. They can be derived from the condensation of carbonic acid with a hydrazine. Carbohydrazide is the simplest carbazide, with another common carbazide being diphenylcarbazide, which is used as an analytical reagent. [1]
An applied example is a synthesis of sunitinib begins by mixing 5-fluoroisatin slowly into hydrazine hydrate. [10] After 4 hours at 110 °C, the indole ring structure has been broken into (2-amino-5-fluoro-phenyl)-acetic acid hydrazide with reduction of the ketone at the 3-position.
Hydrazines (R 2 N−NR 2) are a class of chemical compounds with two nitrogen atoms linked via a covalent bond and which carry from one up to four alkyl or aryl substituents. . Hydrazines can be considered as derivatives of the inorganic hydrazine (H 2 N−NH 2), in which one or more hydrogen atoms have been replaced by hydrocarbon grou

1,2-Diformylhydrazine is the chemical compound with the formula N 2 H 2 (CHO) 2. It is a white, water-soluble solid. A related species is the monoformyl analog, called formic hydrazide (HCON 2 H 3, 624-84-0). As verified by X-ray crystallography, it is a planar molecule with N-N, N-C, and C=O distances of 1.38, 1.33 and 1.24 Å, respectively. [1]
