  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.
