Potassium chlorate, KClO3, is quite oxygen-dense and a potent oxidant. It is used in what we called "whippersnappers" and the suppliers called "Pop-Pops" as kids, along with silver fulminate. There is a singular irony in that the wimpiest firework, the one we could buy even in my solidly blue no-fireworks mommy state, contains two components of some dangerous explosives. But we're talking micro- to milligrams, so don't get any ideas.

Sarin is an organophosphate that irreversibly inhibits cholinesterase. it's a neurotoxin, and a potent one. It'd be absolutely terrifying as a weapon, if it weren't so unstable. Even if a rogue state had gobs of Sarin last year, it's all pretty much a dud by now. The instability of acid halides (carbonyls there, but all of them in general) pretty much ensures this. So the civilized world has that going for it, which is nice.

Trying to think of a molecule tonight, my friend suggested "pick an ugly one no one wants anymore...a clearance rack molecule." I immediately went to chlorinated solvents. They're in the backwater now, right? Carbon tetrachloride sure has a bad rep. I figured most of the organochlorides, except for the ubiquitous lab solvents, would, too. I was wrong.

I love reading lists of fragrance chemicals. The assignment of pleasant, qualitative fragrance descriptions to chemicals with hard-nosed, rigorous functional group names always makes me giggle a little. Acetophenone, for instance, smells of orange blossoms. Today, I came across one that has both in the name: dewy propionate:

If you have been reading SB long enough to remember the DonorsChoose promotion, you might be interested in this. It's videos of scientists talking about their first experiments and why they like science, and if you vote on the one you like best, DC gets a buck. Check it out here.
