On the explosive properties of 1H-benzotriazole and 1H-1,2,3-triazole

For 1H-benzotriazole, no explosive properties are observable, but the relative high exothermic decomposition energy of 1590 J/g should be kept in mind. Nevertheless, an endothermic melting barrier at 100 °C ensures safe handling at lower temperatures. For 1H-1,2,3-triazole, the exothermic decomposition energy is as high as 2600 J/g, but explosive properties are also not detectable. Therefore, both reagents are hazardous with regard to the exothermic decomposition potential and can be handled safely with precautions.
