Produit chimique de formule NH2NH2 ou H2N-NH2 ou H4N2 se présentant sous la forme d'un liquide très toxique, corrosif et miscible à l'eau, fondant à 2 °C et bouillant à 113 °C, fabriqué industriellement par action de l'hypochlorite de sodium sur l'ammoniac ou l'urée.

CONT

[...] l'hydrazine [...] est une base moyenne [...] et un réducteur. Dans ses emplois d'ergol pour fusée, elle est en partie remplacée par la diméthylhydrazine. On l'utilise aussi comme désoxygénant pour l'eau des chaudières, comme agent gonflant des matières plastiques et comme combustible dans les piles à combustible.
