I know! Awesomeness! I just ordered two items which I have no real use for per-se but I see them as chemical collectibles ;)

5g Denatonium Saccharide (extremely/insanely bitter)
1g Nonivamide (synthetic variant of Capsaicin)

Of course as soon as these are received I will stupidly taste test a small dust particle of each for fun hehe

t-butanol! That would be wicked, Ive been searching for some for the longest time and cant find any through my usual supply companies :(

I guess because its spring im doing some spring chemical shopping because I ordered yet again, some are relatively basic things that I cant seem to find anywhere locally:

Malonic acid, 25g Reagent, : This is mainly for demos for friends lol, I am determined to show them the belousov zhabotinsky reaction!

Conc. NH4OH 500ml Reagent: Because these days household ammonia has became about as potent as watered down cat piss with perhaps some lemon perfume in it to make it even less useful for home chemistry.... I had to bite the bullet on this one... 28$ :(

Potassium Iodate 100g reagent: One of the uses will be for the belousov reaction, I know I can make iodate rather easily but im lazy ;) plus its a useful reagent

Conc HCl 500ml reagent: I must have 6 litres of hardware store muriatic, that being said I feel a bit silly paying so much for a small amount but I do need some HCl free of metal contamination for delicate experiments etc.

It annoyed me that I had to purchase reagent grade of this:

CAMPHOR ACS 100g for 15$- I am only 26 yrs old but I remember buying camphor blocks in almost every pharmacy, they were always in some infrequently used low traffic areas of the pharmacies, but they were there! I asked the pharmacist and she said that the company doesnt offer it anymore due to easier to use OTC creams and vapo rubs and god knows what else, of course. Then she told me to check the hardware store... I just came back home.

Also got an eyewash station, Corning PC-420D stir/hotplate (to replace my older PMC hotplate), various brushes, clearance kimax glassware, filter papers, ph papers, 1/4 lb of glass tubing, wash bottles pre-labelled for ethanol, methanol and isopropanol which I love! A second lab stand and some bossheads, glass funnel, claisen adapter and various adapters and a few other things I cant remember... feels like Christmas in April! minus my visa statement when it comes... :S

I'm not sure, nor am I sure I wan't to know :cool:. These were acquired mostly as numerous small orders, although most of the metals were from 2 orders and most of organic compounds (minus the solvents) were in one order, which totalled about $650, although that included shipping (which is always significant for reagents, esp. with hazmat items in different categories having to ship separately).

The total is dominated by the Troy oz. of rhodium sponge, which was about $1350, and required a bank wire transfer. Still, it was only $50 above the rhodium spot price at the time, and compared to the retail prices for relatively small amounts of rhodium compounds (or worse, rhodium-based organometallic catalysts), it seems like a good value. The rhodium is 99.995% pure and is very finely powdered, so it's in ideal condition as a starting material for chemical manipulation to produce one's own rhodium catalysts.

And, before anybody asks, no, I'm not interested in selling any rhodium, or any of my other chemicals, for that matter.

If you don't mind telling us, what's the appeal of the thallium? I guess I can understand if you're an element collector. Is that why? Other than for that purpose, I can't think of any reason why anybody would want that stuff. It's highly toxic, moreso than, say mercury, and is a persistent environmental hazard. I also can't think of any useful chemical properties of the metal or it's compounds that are unique to them and not substitutable by less toxic reagents.

Maybe I'm missing something that makes thallium appealing for more than the collector or the poison maker. If so, what is it?

Purely for element collecting purposes, gallium source just started carrying it recently and I've always wanted a sample just for show :)

That's what I figured. Thinking back over all the old Organic Synthesis papers I've read, online or otherwise, lots of them utilized one or more highly toxic elements (or compounds of those elements), but I don't recall any that used thallium or thallium salts. It certainly wasn't because the authors feared it's toxicity. Some toxic elements are routinely employed: arsenic, selenium, mercury, lead, barium, nickel, hexavalent chromium, etc. Thallium just doesn't seem useful enough to overcome it's inherent dangers. It isn't useless - just search online and lots of chemical or metallurgical uses pop up. It just isn't that useful in the organic chemistry lab.

This reminds me that I forgot a few recent purchases:

100g ThO2
500g Th(NO3)4 * 4H20
50g Br

The nitrate I bought because I got such a good deal on it - a little over $50. If you search around for thorium salts, you'll see what I mean. The oxide, usually called thoria in old chemistry papers, is the more useful compound, IMHO.

Maybe not really spectacular, but rare:

250 grams of sodium phosphite, Na2HPO3.5H2O

Phosphates and sodium hypophosphite are easy to obtain, but phosphite was very hard for me to find, but now I finally have some.

The stuff arrived today, if I have done interesting experiments with this, then I'll certainly add them to my website.

I just ordered a pair of platinum electrodes - the school lab, rod variety usual with Pb, Cu and whatnot. Paid about 23 €, don't know if I made a mistake yet but they were on sale (50% :o) from a reliable supplier.

Also got 10 PE one-litre bottles for cheap while I was at it, and some lead strips.

@Hexavalent,
The tungsten is from eBay. 200g cost me $20 shipped. You should be able to buy it (there are European sellers). It is used for adjusting the floppiness of dog ears (cruel use).

Good value, but I have to agree about its use.

Just out of curiosity, do you know just how it does alter the floppiness of dog ears?
