Synthesis and performance of 7-amino-6-nitro-[1, 2, 5]oxadiazolo[3, 4-b]pyridine-1-oxide

Abstract

Using 2-choro-4-aminopyridine as primary material, a new compound 7-amino-6-nitro-[1, 2, 5]oxadiazolo[3, 4-b]pyridine 1-oxide was synthesized by nitration, azide substitution and cyclization reaction with a total yield of 42%, and its structure was confirmed by 1H NMR, 13C NMR, IR, MS and elemental analysis. Friction and impact sensitivities of the title compound obtained by GJB772A-1997 are 0 and the decomposition temperature is 215.93℃. Results show that 7-amino-6-nitro-[1, 2, 5]oxadiazolo[-3, 4-b]pyridine 1-oxide is a low sensitivity energetic material.
