Toddtracium

From Memory Alpha, the free Star Trek reference.

Toddtracium is, according to the Federation LCARS, a "controllable medium-yield propellant used in small solid rocket motor devices and emergency disconnect explosive bolts."

Toddtracium was available to the crew of the USS Enterprise-D, and was one of the powerful explosives suggested to be used to help free the ship when it was trapped in a Tyken's Rift in 2367. (TNG: "Night Terrors")

Atoms of this material appeared in an okudagram display of explosives listed in the USS Enterprise (NCC-1701-D) library computer.
