4-Hydroxy-3,5-dinitropyrazole (HODNP) was investigated as a precursor for synthesizing two thermally stable, insensitive zwitterionic energetic materials. The ability of the hydroxy functionality to carry negative charge leveraged and further covalently bonded with positively charged moieties (3,4-diamino-1,2,4-triazole acetimidamide) via N-functionalization form zwitterions 2 3. Structural characterization study performance were carried out. nature compound 3 confirmed by single-crystal analysis.

Abstract Due to its good stability, density and oxygen balance, the benzofuroxan fused ring framework has attracted particular attention in field of high energy materials. The planar structure facilitates straightforward derivatization with explosophores contributes molecular stability. In this work, a scaffold was utilized develop highly dense energetic material, namely 5,7‐dihydroxy‐4,6‐dinitrobenzo[c][1,2,5]oxadiazole 1‐oxide ( DHDNBF ). successive inclusion like nitro (−NO 2 ) oxidative functionality hydroxyl (−OH) on resulted an impressive (ρ=1.91 g cm −3 positive balance (6.20 %) Furthermore, hydroxy groups enable formation dicationic salts 3 – 7 , contributing additional modifications overall performance. Energetic 4 5 exhibit significantly higher densities ranging from 1.84 1.87 possess favorable approaching zero or equal zero. A marked improvement thermal stabilities observed all compared their neutral counterparts, . (D v =8459 m s −1 P=32.10 GPa) =8539 P=30.37 performance, comparable that well‐known explosives such as LLM‐105 =8560 P=33.4 GPa). Overall, characteristics make them potential candidates for use benzofuroxan‐based secondary primary explosives, respectively, various military civilian applications.
