I think I'd be willing to hold a small piece of Plutonium in my ungloved hand for a second, I don't think I'd do that with a drop of Dimethyl Mercury:

The former would make a great picture for Facebook !

Yes, it is a shame researchers have not yet developed a chemical synthesis for this lethal enzyme.

I might be mistaken but I though Batrachotoxin (poison arrow frog venom http://en.wikipedia.org/wiki/Batrachotoxin ) was the most potent neurotoxin... I still wouldn't like to try my chances with diethyl mercury like

The lethal dose of batrachotoxin is around 100 micrograms, while the lethal dose for botulinum is around 0.1 microgram.

It looks like Tert-butyl hydroperoxide rates a 4 in each of the NFPA diamonds, as well as the OX (oxidizer) warning.
Of course we are talking the pure substance and not the typical 70% in water which is much more stable.

I'm fairy sure (because i remember reading it, lol), that the flavour of peas is the most potent, 3- methoxy-2-isobutyl pyrazine being 'tasteable' in
peas albeit only there in ppb quantities, this opposed to 'smellable' chemicals which are different.
i may remember it incorrectly but hey you do a google search for 'pea molecule' and see what you get, thats another extreme altogether pardon the pun.
i changed it to 'sweetpea' and got a bunch of hits regarding soppy romantic natural ethereal lovey subjects.

I'm sure they have and I'm sure its unworthy, weapons of this nature are hard to make stronger first of all and making a kilo of a substance that
could destroy the world is not on many people to-do list.
Its like the super potent opiates as weapons, they are just to hard to handle to be considered viable weapons. Sure they have been used in Russia
during terrorist ordeals but there is just not much use in super potent weapons other then fear, that's why we have never seen another use of the
Atomic bomb till this day. Total annihilation goes against what one normally looks for in the conclusion of any conflict, we normally look for total
conformity, destroying our opposition is just a sad side effect of oppressing there will power.
Knowledge is useless to useless people...

before."~Maynard James Keenan

"DNA consists of two long polymers of simple units called nucleotides, with backbones made of sugars and phosphate groups joined by ester bonds. These
two strands run in opposite directions to each other and are therefore anti-parallel. Attached to each sugar is one of four types of molecules called
nucleobases (informally, bases). It is the sequence of these four nucleobases along the backbone that encodes information." -wiki.
A great example neptunium, probably one of the best. This is a great and in depth wiki article on DNA. A great read.

Does graphene count? It's one of the most extreme allotropes of carbon known, with a thermal conductivity exceeding that of diamond and a tensile

T-butyl mercaptan blends which are added to odorless natural gas (cooking uses) and to serve warning of gas leaks.
Note, butanethiol (butyl mercaptan) derivatives are present in skunk secretion.

There is an interesting article here on Butyl Isocyanide regarding the unfathomable odor. Having smelled both butyl isocyanide and methyl mercaptan I think that the butyl isocyanide
wins the prize but the methyl mercaptan gets points for staying power. Still, we could go on about stench for hours, does anyone know the most
phosphorescent compound by chance?

I wasn't being specific because the segue was meant only to put the topic back on track since there is already a whole thread devoted to the worst of
stinks. Phosphorescence just seemed something that is able to be quantified where someone may have known some 'winning' compounds off the top of their
heads.
