Hypergolic

Hypergolic propellant is a type of fuel where the fuel and the oxidizer react on contact. Most are stable at room temperature but highly toxic.

Chemical Equations

Hydrazine = N2H4

Unsymmetrical Dimethylhydrazine "UDMH" = H2NN(CH3)2

Nitrogen Tetroxide "NTO" = NO4

Dinitrogen Tetroxide = N2O4

Aerozine 50 = 50% Hydrazine and 50% UDMH

Monomethylhydrazine = CH3(NH)NH2
