Hydrazine
(gcide) | Hydrazine \Hy"dra*zine\, n. [Hydr- + azo- + -ine.] (Chem.)
Any one of a series of nitrogenous bases, resembling the
amines and produced by the reduction of certain nitroso and
diazo compounds; as, methyl hydrazine, phenyl hydrazine, etc.
They are derivatives of hydrazine proper, H2N.NH2, which is
a doubled amido group, recently (1887) isolated as a stable,
colorless gas, with a peculiar, irritating odor. As a base it
forms distinct salts. Called also diamide, amidogen, (or
more properly diamidogen), etc.

residue of benzene, and the basis of an immense number of
aromatic derivatives.

Phenyl hydrate (Chem.), phenol or carbolic acid.
Phenyl hydrazine (Chem.), a nitrogenous base
(C6H5.NH.NH2) produced artificially as a colorless oil
which unites with acids, ketones, etc., to form easily
crystallized compounds. It is used in organic chemistry,
particulary to isolate compounds in pure form for
analysis.
