The adduct of urea and hydrogen peroxide (UHP) is industrially produced material on a large scale. Although UHP is widely used as a bleaching and oxidizing agent, its properties as energetic material are generally overlooked. In this work we report comprehensive characterization of UHP explosive and thermal properties. We found that UHP is a compound with a negative value of standard enthalpy of formation (- 565.1 kJmol(-1)). It is not sensitive to impact and friction. However, we demonstrated that UHP (1= 0.93 gcm(-3); packed into a steel pipe with inner diameter of 206 mm) detonates with experimental velocity of detonation (VOD) of 3780 ms(-1). Moreover, for UHP with maximal theoretical density (1= 1.43 gcm-3), the calculated VOD reaches 5219 ms(-1). Based on our findings, we recommend that present regulations regarding the handling, storage and transportation of the UHP should be revised, especially in cases, where UHP is kept on a large scale, under confinement and at places where the temperature can reach above 60 degrees C.
