Reminds me of how DNP, a chemical used for creating explosives, has been used as a weight-loss drug. It's surprisingly effective, but overdosing on it will result in a long, hot, agonizing death.

There’s a surprising amount of this. Nitroglycerin is both an explosive and a heart drug, of course, and gunpowder was probably originally developed as an alchemical ‘medicine’.

Really? Doesn't something being explosive mean it's highly unstable and reactive? Presumably ingesting highly reactive reagents is toxic.

Not particularly, no. Some certainly are, but others require a great deal of activation energy to detonate. Nitroglycerine (another explosive medication) is notoriously touchy. But C4 is only mildly flammable; you can heat up your meal by lighting a piece of C4 on fire then put the fire out by smashing it with a hammer; it won't detonate like that.

I’d say this is a pretty unfair assessment. Sure chemotherapy such as nitrogen mustards are still used (because they are effective) but plenty of newer drugs are very targeted.

And it’s not like our approach is all that different for other life threatening diseases. Multi-drug resistant infection? Let me use antibiotics on you that will make you deaf and maybe damage your heart.

"What they found was rapid onset of decomposition at 170 degrees" So this seems to be more about people in a lab situation rather than it being so unstable it reacting sitting in someone's hot car. Suspecting it to react at 212 and finding it reacting at 170 could ruin a lab tech's day to be sure. Those are the jobs that sound fun "for the science" lets see what happens when...

Exactly. Every drug manufacturer has a safety lab where drugs and intermediates are run through a safety evaluation (drop hammer test, heating until decomposition).

This drug is unique in that it’s highly exothermic when it decomposes at 170C, but yeah, not exactly a risky “explosive” to work with.

Sure, but in this context, the drug we're talking about exploded with a drop hammer test, right? That seems more like nitroglycerin than C4.

Maybe helpful to note that the phrase "Class 1 Explosive" isn't denoting a certain type, or power of "Explosive". "Class 1" in Hazmat is all explosives. Class 2 is Gases. Class 3 is Flammable or Combustible liquid, and so on.

Similar to "200 OK", where the number is the important part and the text is just an informative description?

"That a therapeutic drug is explosive..." seems sensationalistic. Reminds me of when people say things like "x contains chemicals used in x!". What's the practical problem with this?

Earlier quoted context omitted.

Nitrogen-Nitrogen bonds inside larger molecules are never quite stable because 1) nitrogen “wants” to form stable di-nitrogen (N2) molecules containing a very stable triple bond (an exothermic reaction) and 2) the result of such decompositions is nitrogen gas increasing the amount of entropy released (due to more molecules being created). Reactions are driven both by the amount of heat released (enthalpy) and the amo…

Does the same apply to oxygen? Since it also likes to be in a diatomic form.

I mean, pure oxygen envs are pretty dangerous on their own, compared to pure N2.
