Synthesis of materials with acceptable performance and low sensitivity to physical stimuli is one of the overall goals of energetic materials. The creation of networks of hydrogen bonds affords good stability to the trigger bonds. In this respect azole-based ionic high-energy materials (especially aminotetrazoles) and other nitrogen-rich compounds have strong hydrogen bonds. Significant stability, insensitivity to a physical stimulus and also good performance are thus created. In this study salts derived from N-(1-carboxymethyl-1H-tetrazole-5-yl)-hydrazinium chloride were synthesized. Anion exchange of the chlorine with nitrate, 5-aminotetrazolate, (5-amino-tetrazole-1-yl)-acetate and (5-nitriminotetrazole-1-yl)-acetate was performed, with precipitation of AgCl. All of the products were characterized using 1H NMR, 13C NMR, FTIR spectroscopy, differential scanning calorimetry (DSC), impact sensitivity and UV-Vis spectroscopy. Among the advantages of this study are the use of methods and available equipment and low-risk solvents during the reaction and the formation of minimum by-products.
