  The chemical decomposition of NTO 1 and its corresponding amine ATO 2 was investigated. To make easier the identification of the decomposition products, we synthesized C-14-labelled NTO and ATO. Our results confirmed the high stability of the NTO triazolone ring. Its scission can be achieved partially by sulfuric acid under intensive heat and pressure. The triazolone ring of ATO was cleaved in alkaline solution. Carbon dioxide is evolved leaving a polar compound assumed to be aminoguanidine. The deamination of ATO was achieved by nitrosation. In dilute HCl (0.15N), 2 equivalents of NO2- lead to the triazolone: Lb, through a radical de-diazotation of the diazo intermediate. With 3 to 10 equivalents of NO2-, the nitrosation leads exclusively to the azide 6.
