Abstract
The novel explosive compound, 1,4-dinitrofurazano[3,4-b]piperazine, is prred by the reaction of 2,3-dioximinopiperazine with a base, followed by the nitration of the intermediate furazano[3,4-b]piperazine. The nitrated compound has a density, detonation pressure, detonation velocity and Isp similar to RDX while being highly insensitive.
