The stability of HAN, HAN derivatives or hydroxylamine, and compositions comprising these is considerably enhanced by employing a stabilizing effective amount of a stabilizer selected from (a) a pyridine or pyridone salt, or an acid thereof; (b) a diphosphonate or methylenephosphonate salt, or an acid thereof; or (c) a mixture of two or more stabilizers, wherein at least one is selected from (a) and at least one is selected from (b). Stabilized HAN, HAN derivatives, or hydroxylamine or compositions comprising HAN, an HAN derivative or hydroxylamine, along with a process for providing these stabilized compositions is described. A stabilizer mixture having enhanced, synergistic stabilizing properties is described as well.

A compound having the following formula: ##STR1## wherein R.sup.1 is --N.sup.+ H.sub.3 as found in claim 1 and R.sup.2 is either the same as F.sup.1 or hydrogen. 'A' is an oxidizing anion, and X is selected to provide a neutral charge balance for the compound. A method of making a compound of the indicated structure from a compound of similar structure by an anion exchange process is also disclosed. Finally, propellant formulations incorporating the novel compounds of the present invention as fuels and oxidizers are disclosed.
