The diacylhydrazines, also known as bisacylhydrazines (BAHs) or dibenzoylhydrazines are appropriately substituted derivatives of dibenzoyl hydrazine. [2] They do not immediately kill the insect, but produces premature unsuccessful moulting, which then causes the death of the insect. BAHs thus belong to the class of insect growth regulators.
Hydrazine sulfate, more properly hydrazinium hydrogensulfate, is a salt of the cation hydrazinium and the anion bisulfate (hydrogensulfate), with the formula N 2 H 6 SO 4 or more properly [N 2 H 5] + [HSO 4] −.
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can be considered as derivatives of the inorganic hydrazine (H 2 N−NH 2), in which one or more hydrogen atoms have been replaced by hydrocarbon grou

In the common names of such salts, the cation is often called "hydrazine", as in "hydrazine sulfate" for hydrazinium hydrogensulfate. The terms "hydrazinium" and "hydrazine" may also be used for the doubly protonated cation [N 2 H 6] 2+, more properly called hydrazinediium or hydrazinium(2+). This cation has an ethane-like structure ([H 3 N− ...
The name "hydrazine" was coined by Emil Fischer in 1875; he was trying to produce organic compounds that consisted of mono-substituted hydrazine. [10] By 1887, Theodor Curtius had produced hydrazine sulfate by treating organic diazides with dilute sulfuric acid; however, he was unable to obtain pure hydrazine, despite repeated efforts.
The benzoyl functional group.. In organic chemistry, benzoyl (/ ˈ b ɛ n z oʊ ɪ l /, BENZ-oh-il) [1] is the functional group with the formula −COC 6 H 5 and structure −C(=O)−C 6 H 5. [2] [3] It can be viewed as benzaldehyde missing one hydrogen.
It is a substituted hydrazine. ... It can be prepared by the reaction of hydrazine sulfate with 2,4-dinitrochlorobenzene: [1] DNP test
