Phthalic anhydride, anyone?

Amos - 12-11-2015 at 21:00

I'm testing the waters for an idea I have: A bulk buy program for U.S. members(potentially international members, too!) that allows people to pay the lower bulk cost of various reagents while only purchasing small amounts. As such, I'm posting to gauge interest for the first buy I plan on doing: Phthalic anhydride!

If anyone would be interested in buying any amount of phthalic anhydride for as low as $5/100g, please reply and give me an estimate of how much you'd want to purchase.

The product in question is 99+% pure, reagent grade, and comes from a chemical supplier in town.

I'd probably be interested in 500g or so. Phthalic anhydride is a vastly useful intermediate and the prep from plasticized vinyl is painfully tedious.

Only U.S members :(?

I hate to bud in like this but I'm also selling phthalic anydride, ACS grade, for 20.00 for 500 grams, if anyone's interested? I also have sodium metal for sale -- 1/2 lb for 80.00.

U2U me if anyone wants some.

I think the idea of a "local chemical purchasing co-op" (for lack of a better name), is great! I think I might be interested in some things, especially as I am just starting to set up a home lab.

I'd take some, but i'm in Spain.

Any sellers ?

Amos - 13-11-2015 at 10:00

I'll definitely sell internationally, it's just a matter of how much the shipping will cost. If you're interested, I can look into the amount of shipping that would be charged, but typically shipping things out of the US costs quite a bit.

aga - 13-11-2015 at 11:37

Price it up for 200g and 500g.

Might be a break point where it works out OK.

Edit:

Ukranian ebay seller has 300g of >= 99% for $27 including shipping.

Would be interesting to see how much from the US to Europe

Phthalic anhydride 99% 1 kg 70 EUR, send worldwide

careysub - 13-11-2015 at 12:31

I'd be interest in 250-500 g.

Amos - 13-11-2015 at 14:38

Great, thanks for the comments, everyone. I think I'll buy about 2-3 kg, and I think I should be able to knock the price down a bit for those that are buying pretty large amounts.

I don't know about Amos and others, but I know that I would be a tad annoyed if I made a thread about selling a product and then others (who as far as I know have never offered to sell said product before) suddenly decide to butt into my thread and offer the same product.

Just my views...

Texium - 13-11-2015 at 22:32

I'm buying 300g... from Amos.

Alright, thanks for the turnout! I'm making the buy early next week and I will begin shipping some time around 11/23/15. In the meantime, I'm accepting orders now and here are the prices:

0-250 g - $5.00 per 100g
251-499 g - $4.50 per 100g
500+ grams - $4.00 per 100g
Shipping depends on location and amount ordered

U2u me with order information and any questions you might have

In addition, here's the link to this sale on SynthSource, a board for buying and selling reagents and glassware started by Praxichys here. It'll serve as a convenient place to find info on future sales like this.

I'm down to my last 350 grams, any takers? Some possible ideas to use it for: luminol, anthranilic acid, phenolphthalein, phthalocyanines, and azo dyes, among others.

Amos,

Thank you for the Phthalic Anhydride. It arrived in good condition and is as pure as you promised.

Would do business again.

:D
