Description and Uses

2-Hydroxyethylhydrazine (HEH) is the primary decomposition product of the high-energy ionic liquid 2-hydroxyethylhydrazinium nitrate (HEHN). As a hydrazine fuel, HEHN is the most widely used liquid monocomponent propellant in the aerospace sector. while HEH is a key target for investigating the reaction mechanism of HEHN.

(2-Hydroxyethyl)hydrazine is used as a plant growth regulant, a component in jet fuels, intermediate for organic synthesis especially heterocycles used in agrochemicals, pharmaceuticals, stabilizers and polymerizations, Chain extender for urethane formulations, corrosion inhibitor.
