The constant-volume combustion energy, cUD(GUDN, s, 298.15 K), enthalpy of solution in acetic ether, solmHQD and kinetic behavior of the exothermic decomposition reaction of the title compound (GUDN) are deter-mined by a precise rotating bomb calorimeter, a Calvet microcalorimeter and DSC, respectively. Its standard en-thalpy of combustion, cmHQD (GUDN, s, 298.15 K), standard enthalpy of formation, fHQDm (GUDN, s, 298.15 K) and kinetic parameters of the exothermic main decomposition reaction in a temperature-programmed mode [the apparent activation energy (aE) and pre-exponential factor (A)] are calculated. The values of cUD (GUDN, s, 298.15 K), cmHQD (GUDN, s, 298.15 K), fmHQD(GUDN, s, 298.15 K) and solmHQD of GUDN are (-7068.64±2.37) J·g-1, (-1467.66±0.50) kJ·mol-1, (-319.76±0.58) kJ·mol-1 and (165.737±0.013) kJ·mol-1, respectively. The kinetic model function in integral form and the value of aEand A of the exothermic main decomposition reaction of GUDN are 220.20 kJ·mol-1 and 1021.18 s-1, respectively. The critical temperature of thermal explosion of GUDN is 217.6 ℃
