HBT is a bistetrazole.^[1] It is an explosive approximately as powerful as HMX or CL-20, but it releases less toxic reaction products when detonated: ammonia and hydrogen cyanide. When combined with ADN or AN oxidizers, the amount of hydrogen cyanide produced by a deflagration may be reduced. The compound is thus considered by its advocates to be a more environmentally friendly explosive than traditional nitroamine-based explosives.
