Sodium bromide seems to have vanished from the pool supplies around here; did I miss something?

Maybe it depends on where "around here" is. It looks like there is some for $7 per pound at Menards:

Part of the reason is that DBDMH is so good at its job. If you look at the mechanism by which it operates, it is quite clever.
https://en.wikipedia.org/wiki/DBDMH
It combines oxidative sanitation with stability and longevity of action.

The fact that it is more difficult to produce free Br2 (accidentally or deliberately) has also pushed the market forces in that direction.

[edit]
I should cut and paste the correct link.

What is the mechanism in a water free environment, such as glacial acetic acid? Is the usual radical bromination mechanism taking place here during the bromination of a carbonyl, where it proceeds through an enol or enolate? This would still result in the production of one equivalent of H-Br for every C-H -> C-Br substitution, correct?

Reason being is that I was told by someone that these hydantoins proceeds through a different mechanism, but they failed to enlighten me.

I would really appreciate a explanation.

j_sum1 - 12-2-2016 at 02:08

Sorry. I only know about their application in spa pools.
Good question though.

The HyperDeath website is offline, but the chemical list lives on at the Internet Archive. https://web.archive.org/web/20150901002855/http://hyperdeath...

I have a pdf of the chemical list on my dropbox too. https://dl.dropboxusercontent.com/u/3621645/Chemical%20List....

Daffodile - 11-3-2016 at 12:35

Who do I talk to if I want to add stuff to the list? For Canadians, there are OTC items not on the list (KNO3, various solvents/ acids, Zinc, Nickel, Manganese, Hydrogen Peroxide, Iodine, etc). I consider myself very good at getting OTC reagents, and it'd be fun to contribute to the list.

dhaffnersr - 30-3-2016 at 15:51

Hello "I am a fish!"

What an amazing piece of work you did putting that list together, I have noticed that a lot of my friends from the UK have a particular harder time procuring chemicals than here in the USA, it's amazing what one can buy even on Amazon.com. Myself, I use a lot of domestic chemicals (supermarkets,drugstores ect,.) which I can use as substitutions, ie,.like using the gas line anti-freeze HEET because it's just methanol, ect.,

Equally ironic though, is a lot of what we, here in the US can buy, can't be shipped out of the USA:(

Again, my hats off to ya my friend, what a great piece of work!

have a good one!

I already purshase some chems by the german seller S3chemicals on ebay.

Very cheap, he also have his own website.

Reagent Shop, a korean one have also plenty of products to but is very expensive.

After, reading the posts associated with the "Readily Available Chemical List" I get the feeling some of us are a bit sensitive... Any Chemist that is not likely going to poison their neighbors or themselves knows how to synthesis most chemicals they would need with a few exceptions.
My opinion is there is never a need or reason to belittle, disrespect, or mock another person. A lot of people want to be chemist and day dream of pulling of the latest recipe for the thrill of it but don't understand the terrible results of a run-away reaction, fire, explosion, poisoning, and deaths accosiated with the use of some chemicals.
True Chemists in my opinion are not the ones to be worrying about, they are not going to scrounge around looking for a few Kilos of chemical.
The Amatuer, Beginner is the one I worry about. They should be very careful and aware of the dangers of chemicals and reactions.
Environmental issues are another topic. Anyone that would leave a bottle, bucket or barrel of lab waste for another person to find or poison the local water way children play in. Doesn't deserve the privilege of chemistry.

(I want to see how you progress in amateur chemistry without the OTC sources)


"My opinion is there is never a need or reason to belittle, disrespect, or mock another person."

(but ...)

(maybe you should consider the pollution caused by professional chemists and the people that they work for as a more significant environmental threat ? )

I wait in anticipation to see your environmentally friendly amateur experiments that need no OTC chemicals,
presumably you can synthesize them out of your rear end
- where your thoughts come from ?

When joining a group it is traditional to politely introduce yourself
- welcome

Has it been mentioned before?

Seems cheap

hexabio - 17-9-2017 at 10:11

I have been using one chemical supplier in the UK for most of my needs.
Realized they have just about everything except for low value liquid reagents.

I just need some simple reagents like pyridine and piperidine at high purity.

Can anyone advise me on a shop that deals with hobbyists and would have these reagents as well as others?

If anyone could PM me and tell me about their experience ordering in the UK that would be great, I came here from the USA 3 years ago and I am finding it very hard to find things I need on ebay, amazon, etc.

Can anyone help?
Thanks!

THF source

Crowfjord - 14-1-2018 at 09:56

I don't think this has been mentioned before. A source for good quality tetrahydrofuran is Techspray conformal coating remover. Straight out of the can it is dry enough for moderate success in Grignard reaction, but after opening should be dried before use. Newark has the best price I was able to find.

Magpie - 15-1-2018 at 10:37

Can THF be used generally in place of diethyl ether? Can it be used for Grignards?

Edit:

I read on wiki that it can indeed be used for Grignards but Et2O is still preferable. What I like about it is that it is OTC as this cleaner and has a bp of 66°C vs ether's 35°C.

I extract my ether from starting fluid by distillation which is a pain and risky as a fire hazard.

The only down-side that I saw was that it is soluble in water where ether is only slightly so.

But $37/pint(250mL) is pricey and $37 shipping makes it prohibitive for me. If I can fin a local supplier I would buy it.

GALCO sells it for $26 plus $17 shipping. I bought it.

Crowfjord - 15-1-2018 at 17:32

Wow, nice find Magpie. I hadn't bought from them in a couple years so I didn't realize the shipping was so much. I'm glad I waited to make a new order. Here's a link to the Galco listing.

I find THF's higher boiling point to be handy with difficult to form Grignards, like those from hindered aryl bromides.

They seem to have multiple different products listed with that title, this one contains nitroethane: https://uk.rs-online.com/web/p/acrylic-adhesives/0144383/

drzdude - 7-3-2018 at 00:27

Can it be isolated? DCM is easy but the other not so much, ever work with nitroethane in water?

Most company,s that seam willing to ship reagents are so expensive jeez quoted 190EU for 1L of propionyl chloride ridiculous considering 1L of 99% + propionic acid is 25EU let alone the MEK route cheaper sources are difficult

Housane - 5-9-2018 at 01:34

Hi i am just wondering where best to get uk chems and if I need a EPP licence. If there is a list on what otc products there are and where to get for uk that would be appreciated.

[Edited on 5-9-2018 by Housane]

monolithic - 15-9-2018 at 06:16

In the near future I'd like to obtain some THF (sufficiently pure for running Grignards) and also trimethyl phosphate and dimethyl carbonate (sufficiently pure for methylation reactions.) They don't need to be ultrapure, just pure enough to reliably run those types of reactions. Does anyone have suggestions for sources that will sell to amateur/home chemists? I have considered distilling THF from plumbing chemicals, I think it was PVC piper joiner, but I'm not sure if it would be pure enough for a Grignard.

[Edited on 15-9-2018 by monolithic]

Boffis - 14-6-2019 at 12:42

Check out some of the new online sites in the UK and I suspect elsewhere for vaping and cosmetic chemicals! 1,3-propanediol, triethyl citrate, various substituted dibenzoyl methanes, pyrazine-methylketone etc.

All sorts of interesting things come up on a google search.

Bumping this.
Just made a purchase from Chemcraft. I have bought via eBay a couple of times and knew they stocked a good range of items. (Really nice element samples of Na and Be.)
There is a wide range of stock in the store, https://chemcraft.su/ and I was delighted with prices and shipping costs. Very worth checking out.

Tellurium - 2-1-2020 at 19:15

I just found this site by chance.
I have no Idea, why you would want to eat aminoguanidine, but I will have other uses for it definately :D
7,5g for under 25€ is quite OK I think. I paid via invoice, that I can pay Up to 14 days after arrival, because at first the website seemed a bit sketchy to me, but it came in Just a few days.
https://www.supersmart.com/de--blutzucker-cholesterin--amino...

Besides the Aminoguanidine the only other ingredient ist rice flour. Right now I'm dissolving the Aminoguanidine HCl from 20 Pills, then I will Filter it and try to precipitate it with NaHCO3. I will let you all know how it turns out and if these pills are indeed legit. If they're not I loose nothing because I have 14 days to pay the Bill and If the stuff is garbage I Just send them Back ;)

Its a strong-ish base. If it did not bubble off CO2 when you added the NaHCO3 you may have made the bicarbonate or carbonate and not the free base.

I have some metformin the double version of the compound with a couple of methyl groups on one of the end nitrogens.

Yes, the bicarbonate was exactly, what I was aiming for, because of its low solubility ;)

Aminoguanidine can be used to make 5-Aminotetrazole, which is a good starting point for various Tetrazole derivatives and that is, what I want to use it for.

Tips on Pricing chems

Brightthermite - 29-7-2020 at 16:03

As of now I have not purchased any really "obscure chemicals", but now Im on the look out for ethylene diamine. The prices are outrageous on sites like fisher sciences. When I was on the hunt for sulfuric acid I found some on https://www.dudadiesel.com/ for 10 bucks a litter. It was 100 dollars for half a litter on fisher and sites like wise! I have no idea how much ethylene diamine would go for. Need some advice on how you all price items and where to look for deals. Thanks!
