diamide
(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.
[1913 Webster] |
Diamide
(gcide) | Diamide \Di*am"ide\ (?; 104), n. [Pref. di- + amide.] (Chem.)
Any compound containing two amido groups united with one or
more acid or negative radicals, -- as distinguished from a
diamine. Cf. Amido acid, under Amido, and Acid amide, under
Amide.
