The electron donating effect of the 4-dimethylamino substituent on the phenyl ring makes this compound one of the more stable of the phenylpentazoles. At room temperature, its chemical half-life is only a few hours, although storage is possible at cryogenic temperatures. The compound was first prepared in 1956[1][2][3] along with other substituted phenylpentazoles. Studies have been conducted on various other derivatives, though necessarily limited by the instability of these compounds.[4][5][6][7][8] Some more highly substituted derivatives, such as 2,6-dihydroxy-4-dimethylaminophenylpentazole, are slightly more stable but conversely, more difficult to make.[9][10] Current research has focused on forming transition metal complexes of these pentazole derivatives, as the pentazole ring should be stabilised by bonding to the metal centre.[11][12][13] References1. ^Huisgen R, I.
