Phenylhydrazine was the first hydrazine derivative characterized, reported by Hermann Emil Fischer in 1875. [ 7 ] [ 8 ] He prepared it by reduction of a phenyl diazonium salt using sulfite salts. Fischer used phenylhydrazine to characterize sugars via formation of hydrazones known as osazones with the sugar aldehyde .
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
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can be considered as derivatives of the inorganic hydrazine (H 2 N−NH 2), in which one or more hydrogen atoms have been replaced by hydrocarbon groups. [1]
Hydrazobenzene (1,2-diphenylhydrazine) is an aromatic organic compound consisting of two aniline groups joined via their nitrogen atoms. It is an important industrial chemical used in the manufacture of dyes , pharmaceuticals , and hydrogen peroxide .
The Fischer indole synthesis is a chemical reaction that produces the aromatic heterocycle indole from a (substituted) phenylhydrazine and an aldehyde or ketone under acidic conditions. [1] [2] The reaction was discovered in 1883 by Emil Fischer. Today antimigraine drugs of the triptan class are often synthesized by this method. The Fischer ...

Like other hydroxylamines it will react with aldehydes to form nitrones, illustrative is the condensation with benzaldehyde to form diphenylnitrone, a well-known 1,3-dipolar compound: [4] C 6 H 5 NHOH + C 6 H 5 CHO → C 6 H 5 N(O)=CHC 6 H 5 + H 2 O. Phenylhydroxylamine is attacked by NO + sources to give cupferron: [5] C 6 H 5 NHOH + C 4 H 9 ...
