Triamino hydrazine (Earth-5875)

Triamino hydrazine is a chemical compound used by the UNSC as fuel.

Use
The root material (N2H4) has been used as fuel for rockets ever since World War II. The compound is compressed in the fuel tanks of thruster packs used by the UNSC Marine Corps and SPARTANs. However, despite its efficiency, the fuel is volatile, being able to cause loss of control to its user.
