hydrazo radical
Noun: A bivalent chemical group or radical with the structure -HNNH-. This group is derived from the compound hydrazine (H₂N-NH₂) by the removal of one hydrogen atom from each nitrogen atom, resulting in a divalent unit that can form links within larger molecules.
The term is used primarily in specialized chemical nomenclature to describe a specific structural fragment within organic and inorganic compounds. * This polymer contains a hydrazo radical in its repeating unit, which influences its properties. * The synthesis involves the insertion of a hydrazo radical bridge between the two aromatic rings.
- In chemical notation, the hydrazo radical is often represented as or , emphasizing its divalent nature and origin from hydrazine.
- It is a key functional group in classes of compounds such as hydrazo compounds (e.g., azobenzene, which contains the azo group, is formally derived from a hydrazo compound via oxidation).
- Hydrazo group: A synonymous term for the hydrazo radical.
- Hydrazine: The parent compound () from which the radical is derived.
- Azo compound: A related class of compounds containing the group, often formed by the oxidation of compounds featuring the hydrazo radical.

The "hydrazo radical" is a specific, bivalent unit. It should not be confused with a free radical in the kinetic sense; here, "radical" refers to a group of atoms that behaves as a unit in chemical reactions.
