dead links in the Lab suppliers

I noticed a few dead links in the wiki section, I don't know if they went out of business or
are otherwise in new places, but it might be worth checking out

Yeah, no point in keeping the suppliers that are out of business. A few needed their links updated. Also added a couple more.

I removed those that are closed for good: Minerals-Water.co.uk, Pyrohub, AusChems, Cynmar, GalliumSource.

However, a few appear to be temporarily closed or their website displays error: Restauro Online, ArgentScientific. I will be keeping an eye on them if they return.

Would you mind cutting the link for ElementalScientific as well? Their site is still up last I knew, but there is little or no equipment or reagents available, and nearly everything has already been liquidated.

I see that there are two new websites linked there. Do you happen to know if they're still of use to chemists or they've changed their business model?

I looked at Carolina Chemical and...maybe it's just me, but it looks like they've switched their model from sales of fairly ordinary chemicals to "get your DEA List I chemicals, sketchy active pharmaceutical ingredients and straight up mislabeled medications here!"

If people agree that this is what they're doing, I'll remove it.

After checking, it seems like a tossup for me. They do carry some DEA listed items, such as the hydride reducing agents, pyridine, AA, etc. (mostly Schedules II and III), but most of the drug-related items appeared to be antibiotics (which are now only approved for consumer sale with a prescription), steroid-related drugs, and low-grade stimulants. Of the ones that I checked, there were no drugs listed that were prohibited by the DEA but were prohibited for consumer sale by the FDA. I could be wrong on this, though.

It seems they do have several useful solvents and reagents, such as AA, sodium borohydride, lithium aluminum hydride, aniline, CS2, chloroform, diethylamine, formalin, peroxide, liquid nitrogen, pyridine, THF, trichloroacetic acid, and TEA.

You seem a little bit confused about some bureaucratic stuff. That's normal. It's in bureaucracy's nature to be confusing and illogical.

The DEA enforces the Controlled Substances Act, which has five "Schedules." These are actual drugs.

The DEA, separately from, but related to these "Schedules," has things called "Lists." These "Lists" have chemicals selected for surveillance as near precursors to chemicals that are on Schedules, and not just Schedule I. 3,4-methylenedioxyphenyl-2-propanone, a List I chemical--it goes under a different name on the site, but that's irrelevant--is on the landing page. I haven't gone through and found all the List I chemicals they claim to sell, but it's more than that one.

Do not remove it; instead, include a warning that the company has included borderline sketchy stuff and as such there is a potential risk in buying from them. I can't find the right wording right now but I suppose you get my meaning.

OK.

One term I'll use and reference is "honeypot."

RIP Cynmar. That was where I got my very first equipment.
