Abstract
Because of environmental and health impacts, there is an ongoing necessity to develop sustainable primary explosives to replace existing lead-based analogues. Now we describe a potential primary explosive, dipotassium 4,6-dinitro-5,7-dioxidobenzo[c][1,2,5]oxadiazole 1-oxide (K
DNDP), which exhibits an excellent thermal stability (
= 281 °C), positive oxygen balance (+4.79%), and a calculated crystal density of ρ = 2.274 g cm
at 100 K. Its physicochemical properties concomitantly with its straightforward synthesis make it a potential replacement for lead-based initiators.
