Nitric acid is an inorganic compound with the formula H N O 3.It is a highly corrosive mineral acid. [6] The compound is colorless, but samples tend to acquire a yellow cast over time due to decomposition into oxides of nitrogen.
Both propellants are extremely dangerous individually: nitric acid is highly corrosive and releases toxic nitrogen dioxide during reactions, or even simply while exposed to air in its highly concentrated "red fuming" form, typically used as rocket propellant. UDMH is both toxic and corrosive.

n.o.s. = not otherwise specified meaning a collective entry to which substances, mixtures, solutions or articles may be assigned if a) they are not mentioned by name in 3.2 Dangerous Goods List AND b) they exhibit chemical, physical and/or dangerous properties corresponding to the Class, classification code, packing group and the name and description of the n.o.s. entry [2]
Furfuryl alcohol + IRFNA (or red fuming nitric acid) – Copenhagen Suborbitals SPECTRA Engine [26] [5]: 27 Furfuryl alcohol + WFNA (or white fuming nitric acid) [5]: 27 Hydrazine + nitric acid (toxic but stable), abandoned due to lack of reliable ignition. No engine with this combination ever went into mass production.
