Interesting uses for Barbital?
Hi all,
I have an acquaintance who works in a blood testing lab. They are throwing out some old lab stuff and reagents which I could get cheaply. Among them
is some sodium diethylbarbiturate for making buffer solutions for electrophoresis.
Now I'm not that interested in electrophoresis and the substance is controlled where I live, so I wouldn't want to keep it around just for the sake of
it. I couldn't find any good ideas what to make with it (online as well as in my literature), so I'd like to ask here, are there any interesting uses
for this reagent? (I don't want to use it as a drug, obviously.) To be more precise, can it be used as a precursor for some other useful reagent or
are there any interesting reaction mechanisms that can be demonstrated using this stuff? Otherwise I'd have to pass up the offer...
Thanks for your ideas,
Fnord

"Throwing out some old stuff and reagents which I could get cheaply"
So this blood testing lab discards controlled substances in the garbage and somebody there is willing to fish it out and sell it to you?
Or is the lab itself actually willing to sell controlled substances to random unlicensed acquaintances of their staff?
Some lab.
Is it owned and run by Kratom3million?

Yep.

Nope.
Care to contribute to the topic?

I think you may be getting a little over-paranoid in the wake of the
trolling.
Honestly it wouldn't surprise me if the OP is telling the truth. Sometimes labs can be surprisingly lax about securing things, especially when it
comes to things that they don't need. For what it's worth though, don't bother with the barbital. Anything interesting you could prepare with it is
likely also a controlled substance, so it's not worth it.

I would find it more than surprising if labs weren't legally required to account for scheduled substances in their possession in order to keep their
licensing to work with those substances.
And avoid ruinous fines.

Thanks for the your reply, zts16.
The stuff in the lab has probably been tucked away in the basement for maybe decades and I am of the impression that nobody there knows what it all is
or even gives a s**t about it. I could even get sodium azide from there, but no thanks 
I'll leave the Barbital and take some of the fine glass ware

It's not as if barbital buffers are hat unusual.

Unusual doesn't enter into it.
The controlled nature of this substance he was asking if he should get was what attracted my attention.
2,5 dimethoxyamphetamine used to be as common as dirt in some industries, but I doubt they let the employees take it home with them, or sell it off to
their friends.

Does it keep for decades just out of curiosity?

Here in the UK there has been alot of news about schools, many have had to call in the bomb squad recently because of stocks of old chems. I have no
idea what the chemical was now, but alot of schools still had it from the 70's and 80's.
If your interested then a google should throw the story up on the BBC website, as it was a pretty big news story. Alot of my glassware came from old
university departments that were clearing out, i was offered boxs of chems where alot of the labels could hardly be read. I didnt take the chems,
mainly because i couldnt fit anything else in the car.
The point is, at least in the UK there is many places that seem to be alot less careful with things than you would imagine.

Or not.
The substance was dinitrophenylhydrazine.
It has been used for decades.
Suddenly they somehow realised that you can make it explode.
So, because they are much more careful than they need to be, they got rid of it.
Incidentally, could you hydrolyse barbital then decarboxylate it to something like diethyl acetic acid?
2-ethylbutanoic acid
Not sure it's any real use.

That chemical that requires bomb squad disposal is likely picric acid or more likely 2,4-dinitrophenyl hydrazide aka Brady's reagent. My guess is that
if there are no heavy metals around, i. e. in the cap or in the liner thereof, they are not really that dangerous. But what worth are guesses in the
light of dismemberment.

This post is odd, why is it nested in unionized 's post...
