CAS-Nr.：19718-92-4 to trade
Hello guys,
got up to 200g of
4-(Dimethylamino)butyraldehyde Dimethyl Acetal CAS-Nr.：19718-92-4 >97.3 %, GC avaliable
to share. If you like some, I'm always in the mood of new glassware or other fancy stuff (I do not sell).
I already wrote nearly the same post here so if it is considered as a double please delete one.
I really did not pay much and I do not want to make buisness. Most vendors do sell this chemical too expensive in my opinion, more kind of rip off so
let´s see some nice Claisen-Eschenmooser soon I hope
u2u me if you are interested.

Ok changed my mind, I am willing to sell the appx 200g for 5$ per gram. excl shipping and packaging no matter how much you want. shipping within
europe is no problem.
Edit: oops i did it again, it´s 3$ per g

You can do a Fischer indole synthesis with 4-x substituted phenylhydrazines or eschenmoser-claisen rearrangement should be possible. I had a good
example for the eschenmoser but I do not find it atm, sorry, I will post it as soon as I find it again
Fischer indole example can be found in the rhodium archieve

Then, out of the blue, when it is most unexpected, something very different presents itself.

Well, thats exactly the way I felt on getting the wrong chem. Sadly illigal to synthesise, this would be the way to use your "on-board reactor" if one likes to play on his own chemistry anyway.
Nice comic thx

Isn't that CAS 1116-77-4?
Also, € 3 per gram is what you can get from suppliers in general — Even 2 €/gram if you buy 25 g of it

No it isn´t. You mention the diethyl acetal, I posted the dimethyl acetal.
The methyl is at 167 eur per 25g on tcichemicals.
And even in larger amounts it´d be about 1 eur per ml as far as I know.

Oh, my bad. Sorry.
PS: what justifies such a price bump?

In the fischer the acetal has to undergo hydrolysis first, maybe the methy hydrolyses more readily than the ethyl under those conditions. But actually
I dont know. Quite large difference for nearly the same compound, I think even the same manufacturing route except for the MeOH/EtOH swap.
