Hydrazine is an inorganic compound with the chemical formula N 2 H 4.It is a simple pnictogen hydride, and is a colourless flammable liquid with an ammonia-like odour.Hydrazine is highly hazardous unless handled in solution as, for example, hydrazine hydrate (N 2 H 4 ·xH 2 O).
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can be considered as derivatives of the inorganic hydrazine (H 2 N−NH 2), in which one or more hydrogen atoms have been replaced by hydrocarbon grou
Unsymmetrical dimethylhydrazine (abbreviated as UDMH; also known as 1,1-dimethylhydrazine, heptyl or Geptil) is a chemical compound with the formula H 2 NN(CH 3) 2 that is primarily used as a rocket propellant. [4]
Formylhydrazine is a chemical compound with the molecular formula CH 4 N 2 O and it has a mass of 60 g/mol. It is also known as formic acid hydrazide, hydrazinecarboxaldehyde, formohydrazide, or formic hydrazide.
Later randomized controlled trials failed to find any improvement in survival, [27] [28] For example, in a trial of the treatment of advanced lung cancer, with either cisplatin and vinblastine or these drugs plus hydrazine sulfate, saw complete tumor regression in 4% of the hydrazine group, versus 3% in the control group, and tumor progression ...

DNPH is a red to orange solid. It is a substituted hydrazine. The solid is relatively sensitive to shock and friction. For this reason DNPH is usually handled as a wet powder. DNPH is a precursor to the drug Sivifene.
Industrially the compound is produced by treatment of urea with hydrazine: [3] OC(NH 2) 2 + 2 N 2 H 4 → OC(N 2 H 3) 2 + 2 NH 3. It can also be prepared by reactions of other C1-precursors with hydrazine, such as carbonate esters. [2] It can be prepared from phosgene, but this route cogenerates the hydrazinium salt [N 2 H 5]Cl and results in ...
