Chemicals for Sale even rare or exotics for the best cost!
Hello dear Sciencemadness member.
I have been a Sciencemadness member since 2016 and I'm aware of the difficulties some members have in getting certain chemicals. Although I started on
this blog as an amateur, today I run a chemical and pharmaceutical company and I'm able to import and export the chemical you need, as long as they
are not drugs, chemical warfare agents or those whose trade is prohibited by international conventions. I have the best prices on the market and I
guarantee the delivery of the chemical in your hands quickly and safely, guaranteeing your money back if you are not satisfied. Hey, any resemblance
to @Mario840 is not just a coincidence, heh, heh. I was his client years ago! Let's be partners? make your quotation with me by U2U, without
compromise, and solve definitively your problems in how to acquire certain reagents, even those rare and exotic, difficult to find, with the lowest
cost, speed and safety at your hands. I Work with Pay Pal (international credit card) for your convenience and safety.

Come on guys, don't be so shy!
Make a quotation with me by U2U without compromise. Until now just a few members did it.
I am giving examples of selling prices of strong bases and reducing agents commonly used in chemical synthesis:
NaNH2 - Sodamide (98%) - USD105,00/100 grs (CAS Nº 7782-92-5)
KOTbu - Potassium Tert-butoxide-USD120,00/500 grs (CAS Nº 865-47-4)
LiAlH4 - Lithium Aluminium Hydride (98%)-USD135,00/100 grs (CAS Nº 16853-85-3)
Al(O-i-Pr)3 - Aluminium Isopropoxide-USD60,00/1 kilogram (CAS Nº 555-31-7)
NaBH4 - Sodium Borohydride*
*@Loptr is selling it for USD0,50/gr. I think he has the best price and you should buy from him: http://www.sciencemadness.org/talk/viewthread.php?tid=84055.
Thanks.

Piperonal precursor:
Piperonyl alcohol 98% - USD500,00/500grs (CAS nº 495-76-1)
benzodiazepinics precursor:
Ethyl ester hydrochloride glycine 99% - USD100,00/500grs (CAS nº 623-33-6)
Sodium thiopental ( Pentothal) (Truth serum) precursors:
Diethyl ethylmalonate 99% - USD135,00/500grs (CAS nº 133-13-1)

You might want to be careful about how you sell those precursors, especially if your country has an extradition policy with e.g. the USA.

Hey, @Monolithic,
I'm not selling watched precursors, but only non watched precursors of precursors. I'm only giving an idea (for nuts ) that substances can be used as start point to synthesizes the final target, but you
can use them for a lot of licit purposes.
Thanks anyway.

I agree with you @Karlos. The price is just a little below Sigma Aldrich charges me. I will complaint with my supplier to request better prices for
it, although she offers 99% purity grade.
Thanks for the notation.

That's not really much of a starting point for drugs.i know in America you'd get life in prison for intent to manufacture but in reality your still a
long way off.and who makes benzos? Just go to the doctor.

Hey man, why so much aggressiveness? I'm just trying to help other members here that can not purchase chemicals so easier. My intention here is not
profits. Like as I've said, I'm satisfied enough with my profits selling to my national customers.
If you read my first post at this thread I'm sure that been stated clear I don't sell drugs, chemical warfare agents and/or chemical prohibited by
international conventions.
Don't worry with my freedom at all. I'm not a little child and know to take care well of myself and better yet what I can and cannot do by
international laws.

Oh well, You can look for at Thomas Scientific, Carlos Erba, Alfa Aeser, Acros, Sigma Aldrich and other international suppliers like that, if are
easier for you purchase from them as a person, not as company. Then if you find a price lower than mine you should post it here or complaint, like
@Karlos did. May be I could get with my supplier a better price or, at least, I could add another supplier to my list of business relation ship, to
still trying to help another Sciencemadness members here, that can not buy chemicals as a company.

Are you limited to just chemicals? In the US, the glassware brand Quickfit might as well be imaginary. I am looking for a Quickfit made Dufton
fractionating column in B24 ( Standard taper24/29) with a effective length of 300 mm. it has sentimental value to me, I admit. If not thanks and stick
around: We need all the chem suppliers we can get.

Unfortunatelly I'm working only with chemicals here. At my country I sell borosilicate and quartz glassware too cause I have two manufacturers friends
of mine that can build every kind of piece you can imagine for labs with good prices.
But I took a look at the web for you trying to find your sentimental glassware
and found a supplier in UK selling that for USD219,00 (https://www.timstar.com/qfc1-12-fractionating-columns-quickf...) and another in India, but he don't give the price at the announce (http://www.shivsons.com/product/fractionating-column-dufton/).
At E-bay there's an Australian supplier selling this Dufton glassware but only with 250mm length. It's a good price, I guess: AU$39,99 plus USD31,50
shipping price to USA (https://www.ebay.com.au/itm/DUFTON-COLUMN-250mm-medium-/1631...).
Hope that could help you and thanks for your support. You're a nice guy.

The point I was making is piperonal could probably be bought much cheaper than that especially when you consider what kind of yeilds you'd get going
from alcohol to aldehyde.

I agree with you, Piperonal is cheaper, but is also an watched precursor and I can't sell it, like I've said at the announce. This price is what my
supplier is charging me plus 20% profits, which I judge fair.
But come on, you can buy with me just 100 grams instead 500 grams of piperonyl alcohol for only USD120,00.
Transforming alcohols into aldehydes is one of my favorite topics here in Sciencemadness and exists a lot of discussions inside threads here I have
given my contribution with papers. My preferred methods are to use cheaper calcium hypochlorite an alumina to get around 90% or a moffat oxidation
using phosphorous pentoxide, DMSO, DCM and TEA getting around 85% at room temperature that works with diols too, oxidating the two hidroxyl groups at
the same time without clevage, among other methods that you can find doing a research at Organic Chemistry section.

Here is Piperonyl alcohol for 216 EUR per 500g
https://www.tcichemicals.com/eshop/de/de/commodity/P0457/
NBS is freely available in Germany, 500g for 44 EUR.
I'm wondering, since you sell also locally if you could negotiate
more fair prices as a regular customer. The online prices without login at Sigma, Merck, VWR etc. are usually already three or four times the "normal"
market price.
Ususal price for SOCl2 schould be 20 EUR per liter, or benzene 13 EUR a liter. I mean the "normal" prices, a university or so would pay.
I know, this is not in reach for most, but with your prices I fear you won't get a lot of buyers here.
I'm spoiled by prices in Poland anyway (locally, not online). Got half a liter of bromine (technical) for 7 EUR in Poland for example. Simple solvents
like n-Butanol, n-Propanol for 5 EUR/liter. Etc.pp.

The question is not that simple. TCI sell only to companies (or universities), and you have to fill in a registration. They not sell to individuals.
The prices is VAT not included for European area and they charge you with fees to import the chemicals not to mention importation taxes, broker
payments, shipment cost, etc.
Is the same case that why the fuel prices is so cheap when comes out the petroleum refinery but so expensive when we buy it at the gas station to fuel
our vehicle.
Buy from TCI may be easy for you, but not for the majority numbers of Sciencemadness members that should buy chemicals as individuals with all
government restrictions imposed to do that. As I've said, I'm not looking for profits here, just to help. On the other hand, I won't work for free.
Nobody do that.
I understand your point of view. May be TCI Americas could be a good supplier for my company, to sell to my regular customers and I'm thankful to you
for remember me about TCI Americas as a supplier, cause I was quite forgetting about them. Truly, I never registered my company with them, just did
some on line quotations a few times ago.
But you must agree with me that all the logistics involved in sending chemical products to members of sciencemadness is quite different from a normal
export that I would do to another company elsewhere in the world and so it has different costs and that raises the price of the product.
So I am avoiding posting new quotes here, preferring to ask members to send me a U2U, so that I can analyze case by case and look for the best price
and shipping method.
But anyway, thanks for your sincerity.

If you're getting 85-90% yeilds I suppose that makes it doable if you've a need for it.
As far as the prices in Poland they are extremely cheap.
