7-amino-6-nitrobenzodifuroxan (ANBDF) was synthesized through three reactions from starting material 3,5-dinitrobenzoic acid with high yield. ANBDF molecule contains one amino-group, one nitro-group and two benzofuroxan rings that are on the benzene ring and are on the same plane. This particular structure characterizes its high thermal stability. The results of TGA and DSC show that ANBDF is an excellent explosive with high thermal stability.
