Organic Derivatives of 5-Azidotetrazole

5-Nitro-2-picryltetrazole can be prepared by the reaction of picrylchloride with sodium salt of nitrotetrazole in acetone. When water is present, picric acid is formed, casting doubts on the hydrolytic stability of the picryl derivative [4]. 

Organic derivatives of 5-azidotetrazole have been reported by Friedrich [99]. They are more stable and less sensitive than the metallic salts. The methyl and ethyl derivatives are very strong igniting explosives. Ethylene tetrazylazide, that forms an oily liquid, possesses extraordinary brisance and is easily ignited by spark and flames. It easily gelatinizes nitrocellulose [1,99]. Impact sensitivities of 5-azido-l-methyltetrazole and 5-azido-l-picryltetrazole in comparison with the copper salt are summarized in Table 8.19 [79]. 

Organic derivatives of 5-azidotetrazole can be prepared from the alkali salts of 5-azidotetrazole and organic chlorides of sulfates [99].
