FIELD: chemistry.
SUBSTANCE: invention relates to 3-(3,5-dinitropyrazol-4-yl)-4-nitrofurazan of formula I, method of its obtaining and its application as thermostable explosive substance. 
. Method of obtaining lies in interaction of 3-nitrofurazan-4-acetic acid with mixture of dimethylformamide and phosphorus chloroxy, with further processing of reaction mixture with water acid solution, or its alkali or alkali earth salt, obtained salt of trimethyn derivative is processed with hydrazine or its derivatives, with further nitrating of obtained 3-(pyrazol-4-yl)-4-nitrofurazan with sulphur-nitrogen nitrating mixture at heating.
EFFECT: compound of formula I can be applied as component of explosive compositions, solid propellant and power-intensive compositions for various purposes, used at higher temperatures.
