1,2,4-Butanetriol trinitrate

1,2,4-Butanetriol trinitrate (BTTN), also called butanetriol trinitrate, is an important military propellant. It is a colorless to brown explosive liquid. BTTN is used as a propellant in virtually all single-stage missiles used by the United States, including the Hellfire. It is less volatile, less sensitive to shock, and more thermally stable than nitroglycerine, for which it is a promising replacement. BTTN as a propellant is often used in a mixture with nitroglycerin. The mixture can be made by co-nitration of butanetriol and glycerol. Wikipedia
