Diagram of a molecule of this compound (top).
Moyerite (Synthetic) was a semi-solid propellant used by Federation starships for their ullage thruster devices and emergnecy jettison thrusters. This propellant has an extremely fast ignition rate. This propellant had a relatively low specific impulse (450 isp) and a shelf life in excess of ten standard years without a significant deteoriation of performance. In 2367, this propellant was stored on aboard the Federation starship USS Enterprise-D.
In that year, Moyerite (Synthetic) was on a list of explosives that Lieutenant Commander Data and Counselor Deanna Troi searched through in an attempt to find one that could produce enough energy to release the USS Enterprise-D and an alien ship from the Tyken's Rift. (TNG: "Night Terrors")
