BTTN is used as a propellant in virtually all single-stage missiles used by the United States, including the Hellfire.[2] It is less volatile, less sensitive to shock, and more thermally stable than nitroglycerine,[3] for which it is a promising replacement.[4]

BTTN as a propellant is often used in a mixture with nitroglycerin.[3] The mixture can be made by co-nitration of butanetriol and glycerol.[5] BTTN is also used as a plasticizer in some nitrocellulose-based propellants.[6]

BTTN is manufactured by nitration of 1,2,4-butanetriol.[7] Biotechnological manufacture of butanetriol is under intensive research.[8]
