The compound is an ionic compound consisting of a cation NH(subscript 4 superscript +) and an anion C6H2N3O(subscript 9 superscript -), and it is the mono-substituted salt of TNPG. Since the existence of complicated hydrogen bond networks and electrostatic attraction between NH(subscript 4 superscript +) cation and C6H2N3O(subscript 9 superscript -) canion, the compound possesses better stability and low sensitivity.

该化合物是由一个铵根离子与一个一价的三硝基均苯三酚负离子相结合而形成的离子型化合物，分子中存在的大量氢键及铵根离子与三硝基均苯三酚负离子之间的静电引力使得该化合物具有较高的热稳定性和较低的感度。

Both of them showed no toxic effect on mice at the testing dose of 10 mg/kg. The 2,2-diphenyl-1-picrylhydrazyl free radical scavenging test showed that both of the formicary extracts were potent radical scavengers and their scavenging activities were dose-dependent. Furthermore, at higher concentrations (5～10 mg/ml) both of them exhibited significantly higher DPPH scavenging activity than butylated hydroxytoluene.
