Hydrazinium nitroformate (HNF) is a salt of the hydrazinium ion (N2H5+) and nitroformate (C(NO2)3-). It is an energetic oxidizer, and is soluble in most solvents. Research is being conducted at ESA, to investigate its use in solid rocket propellants. It tends to produce propellants which burn very rapidly and with very high combustion efficiency. Its high energy leads to high specific impulse propellants. It is currently an expensive research chemical available only in limited quantities. A disadvantage of HNF is its limited thermal stability.
