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).
The most common use of monopropellants [3] is in low-impulse monopropellant rocket motors, [4] such as reaction control thrusters, the usual propellant being hydrazine [5] [6] which is generally decomposed by exposure to an iridium [7] [8] catalyst bed (the hydrazine is pre-heated to keep the reactant liquid).

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can be considered as derivatives of the inorganic hydrazine (H 2 N−NH 2), in which one or more hydrogen atoms have been replaced by hydrocarbon grou
IUPAC states that, "As one of its major activities, IUPAC develops Recommendations to establish unambiguous, uniform, and consistent nomenclature and terminology for specific scientific fields, usually presented as: glossaries of terms for specific chemical disciplines; definitions of terms relating to a group of properties; nomenclature of chemical compounds and their classes; terminology ...
Hydrazine sulfate has a number of uses in chemical laboratories and in the chemical industry, including analytical chemistry and the synthesis of organic compounds. In those uses it is usually preferred to pure hydrazine, because it is not volatile and is less susceptible to atmospheric oxidation on storage.
The representative examples would be high nucleophilicities of hydroperoxide (HO 2 −) and hydrazine (N 2 H 4). [3] The effect is now well established with numerous examples and became an important concept in mechanistic chemistry and biochemistry. [4] However, the origin of the effect is still controversial without a clear winner.
For example, the compound LiBr is made of Li + cations and Br − anions; thus, it is called lithium bromide. The compound BaO, which is composed of Ba 2+ cations and O 2− anions, is referred to as barium oxide. The oxidation state of each element is unambiguous. When these ions combine into a type-I binary compound, their equal-but-opposite ...
