This is the first line on Wikipedia:

Cyanuric triazide ($\ce{C3N12}$ or $\ce{(NCN3)3}$) is described as an environmentally friendly, low toxicity, and organic primary explosive with a detonation velocity of about $\pu{7300 m/s}$, and ignition temperature at $\pu{205 °C}$

While it is written in the general WP article that "some" organic azides are classified as highly explosive and toxic (and citing the article in ref.), I want to know what determines its toxicity and why cyanuric triazide is less toxic?

Reference

    $\begingroup$ Umm, it's rather a relative thing. Well, for example KCN is much less toxic than botox ;> $\endgroup$

  • $\begingroup$ Two differences from most organic azides: no hydrogen, and carbon is in effect fully oxidized (all four valence are to more electronegative atoms). $\endgroup$ Commented Jan 8, 2023 at 23:45
  • $\begingroup$ When you try to look up toxicity info for organic azides, they are often limited. Further, I read in one source that little data has been recorded for the toxicity of the majority of organic azides. The toxicity of sodium azide or hydrogen azide comes with the release of the anion which disrupts cellular processes. $\endgroup$
