A new high-energy compound 3，4-bis（（4-chloro-3，5-dinitro-1H-pyrazol-1-yl）methyl）-furoxan was synthesized by using 4-chloropyrazole as raw material， and its single crystal was obtained by solvent evaporation. The structures of this compound and its intermediates were characterized by ¹H and ¹³C NMR， FT-IR， DSC and TG， and the crystal structure of the product was characterized by X-ray single crystal diffraction. Results show that the compound belongs to the orthorhombic space group Pbca， a=10.1817（7） Å， b=16.1917（11） Å， c=21.7300（16） Å， V=3582.4（4） ų， α=90°， β=90°， γ=90°， Z=8， D_c=1.836 g·cm^-1. The Kamlet-Jacobs semi-empirical equation was used to predict the explosion velocity of 8304 m·s^-1 and the explosion pressure of 30.5 GPa. The sensitivities of this compound were measured by the BAM standard method， and the measured impact sensitivity is 9 J and the friction sensitivity is 180 N.
