Monomethylhydrazine (MMH) is a highly toxic, volatile hydrazine derivative with the chemical formula CH6N2. It is used as a rocket propellant in bipropellant rocket engines because it is hypergolic with various oxidizers such as nitrogen tetroxide (N2O4) and nitric acid (HNO3). As a propellant, it is described in specification MIL-PRF-27404. [5]

N2O4/MMH propellant. Monomethylhydrazine (MMH) is a storable liquid fuel that found favor in the United States for use in orbital spacecraft engines. Its advantages in comparison to UDMH are higher density and slightly higher performance. Specific impulse: 336 s. Specific impulse sea level: 288 s. Optimum Oxidizer to Fuel Ratio: 2.16.

MMH, Monomethylhydrazine. Fuming, colorless liquid with an ammonia-like odor. Class IB Flammable Liquid: Fl.P. below 73°F and BP at or above 100°F. Oxides of iron; copper; manganese; lead; copper alloys; porous materials such as earth, asbestos, wood & cloth; strong oxidizers such as fluorine & chlorine; nitric acid; hydrogen peroxide.

Methylhydrazine appears as a colorless liquid with an ammonia -like odor. Flash point below 75 °F. Spontaneous ignition may occur in contact with oxidizing materials. Very toxic by inhalation and by skin absorption. Produces toxic oxides of nitrogen during combustion.

Methyl hydrazine is the strongest convulsant and the most toxic of methyl-substituted hydrazine derivatives. It is more toxic than hydrazine. At high doses, it is a strong central nervous system poison that can lead to convulsions and death. Skin rash may be aggravated by skin exposure. (EPA, 1998) METHYLHYDRAZINE is a powerful reducing agent.
