BTTN is used as a propellant in virtually all single-stage missiles used by the United States, including the Hellfire.[3] It is less volatile, less sensitive to shock, and more thermally stable than nitroglycerine,[4] for which it is a promising replacement.[5]

BTTN as a propellant is often used in a mixture with nitroglycerin.[4] The mixture can be made by co-nitration of butanetriol and glycerol.[6] BTTN is also used as a plasticizer in some nitrocellulose-based propellants.[7]

BTTN is manufactured by nitration of 1,2,4-butanetriol.[8] Biotechnological manufacture of butanetriol is under intensive research.[9]
