hydrazonen.

/ˈhʌɪdrəzəʊn/

Etymology: < German hydrazon (E. Fischer 1888, in Berichte der Deutsch. Chem. Ges. 21 984), < hydraz- (in hydrazine n.) + -one suffix.

Chemistry.

Any compound which contains the group N·NH₂ (attached to a single carbon atom) and which is thus a condensation product of an aldehyde or ketone with hydrazine; also, any substituted derivative, N·NHR or N·NRR′, of such a compound.

hydrazone1888

1888 Jrnl. Chem. Soc. 54 590 The name hydrazone is proposed for the compounds of hydrazine with aldehydes and ketones.

1893 Jrnl. Chem. Soc. 64 i. 461 Bülow's test for hydrazones depends on the formation of a tetrazone and its subsequent reaction with sulphuric acid.

1938 C. F. H. Allen & A. H. Blatt in H. Gilman Org. Chem. I. vi. 569 Oximes, hydrazones, and phenylhydrazones are utilized primarily for isolating and identifying carbonyl compounds.

1970 Nature 5 Sept. 1048/1 Experiments..suggested that the hydrazone side-chain of rifampicin was essential for its antiviral activity.
