6-APB (1-(benzofuran-6-yl)propan-2-amine) CAS number?

^ I had a suspicion that that may be the case, they were received from different people though.

I had been told that a lot of NMR reports do look similar and hadn't checked thoroughly to see if it was identical.

each NMR machine and each NMR run is unique they all run at slightly different frequencies and have different locks and tunes and probes they also use slightly different solvents, it is easy to see it if you know.

even the same sample run on different machines will give very slightly different results because each machine has a slightly different magnetic field and therefore slightly different peak shape. the peaks however will be in the same place and be the same relative size.

in the above case you don't even need to be that clever, there is a distinctive double peak on the very upfield end right end of the spectrum probably because the NMR operator was clueless, one is probably TMS though why it was eccessary to use TMS as a internal lock is beyond me.

we have the same NMR analysis being presented as different things, the whole thing is just bullshit.

the same applies to the original NMR, that is a sample where we don't know if the sample is representative of the bulk material and additionally is an NMR supplied by somene with a vested commercial interest in the substance.

this whole 6-ABP thing is a complete farce, there are no such things as official vendors of RC's despite what certain people (who perhaps have ulterior motives) seem to want to suggest, they are all unofficial, all irresponsible, all shady and all illegal. There is no quality control, no toxicology and it is just bad.
 
^Really ALL these questions were answered in my 2nd last post :\

Again:
- The impurities come most likely from an amateurish purification procedure and include both solvents AND synthesis intermediates. Synthesis discussion is verboten here, so you have to find out on your own what the usual synthesis are, and therefore, how the expected intermediates look like.
- The exact nature of the impurities is uncertain, but most likely contains acetone + X.
- The risk when ingesting this batch without further purification are...goddamnit uncertain. Take some (...nah! take A LOT!) and find it out! NOBODY can tell you what these impurities are nor what they can cause.

The easiest way for purification is in my opinion recrystallisation of the (presumable) 6-APB salt. See Vogel's Handbook (copies are available online) for standard procedures.

DO NOT INGEST THIS BATCH WITHOUT FURTHER PURIFICATION! If you have any further doubts about this warning please read the story about how MPTP was discovered. Like to be the next guinea pig for the RC community? Go ahead...

Is it possible to do this without any chemistry knowledge/material (or easy to get material)? Dont know much about it, but if its possible to purify my material easily id like to know.

just read his post?

try googling that and think if you understand what is written there. When you dont understand a word let it be.

You could also try to wash with cold acetone but since nobody have a idea what the impurities are this could also result in loss of product and even more impurities for your body.

I would just dont touch this shit until some months have past and the production is done more profesionaly.
 
Thx, just wanted to know wheter its something worth bothering with without any previous knowledge of such things, i'l take a look.
 
Is it ok to talk about what possible precursors might be left in this as impurities? The only limited information i could find is that possibly psoralene or coumarin could be involved from the start and i don't know anything about what intermediaries could be made after that.
 
this is really not the place to discuss the synthesis nor the possible impurities, because it conflicts with the forum policy and it is based on analytical data from dubious sources.
 
Was going to post NMRs here, but I see that you've already seen them.

For the record I ordered 1g of this before reading this thread (won't be taking it now:p )

Here is what it looks like:

White, crystalline.



dissolved a bit in water.. I estimate at least 10% did not dissolve, but either stayed on the bottom, or floated on the top.
 
random NMR's,
Now random pictures of random powders 8)

please someone post something useful
 
in the interests of signal to noise in this thread please keep the discussion advanced. If you want to post noise post it in the PD trainwreck thread.
 
I have some of the unpure 6-apb, and I'm not willing to consume it after reading this thread. (Thanks you may have saved my life). I would just like to know how can I recrystalize 6-apb. What solvent should I use? I tried google and nothing useful came up.

If this doesn't belong here feel free to delete or move it mods. Cheers.

*yawn* Hate to repeat myself: Get a copy of Vogel's and read the section about recrystallisation. It's the best introduction to this topic I've seen so far.

Proper 6-APB NMR??

Have received this NMR from a vendor, saying that it is the NMR of his 6-APB batch.



Uploaded with ImageShack.us

Can anyone who is able to read NMRs tell me if this is actually an NMR of 6-APB and if this batch is supposed to be good quality or not.
I post this in the ADD as I believe this to be the place where the most people that can read NMRs are located.

Thank's!

Mods please merge this with this tread if possible. I'm loosing the overview...

Thanks a lot!

P.S. No, it's not 6-APB! With certainty. Signal assignment will follow.

P.P.S:
Signal assignment so far as it makes sense:
(chemical shift [ppm] - Integral - Signal splitting - coupling constant [Hz]: assignment)

1.31 - 3 - triplett - 6.8 Hz: -CH3
2.01 - 3 - singulett - -: -CH3
3.97 - 2 - quartett - 6.8 Hz: -CH2-
6.84 - 2 - dublett - 8.8 Hz: 2xAr-CH
7.46 - 2 - dublett - 8.6 Hz: 2xAr-CH
9.76 - 1 - singulett - -: NH, OH, COOH or alike

Interpretation:
  • Signals at 1.31 and 3.97 ppm belong together, ergo is an ethyl-chain present. Downfield-shift of the CH2-part suggest binding to a heteroatom (e.g. ester, ether or amine).
  • Signals in the aromatic range (6.84 & 7.46 ppm) look like a para-substituted phenyl-ring.
  • Methyl-signal at 2.01 ppm is too far highfield shifted to be connected to a heteroatom, so maybe one of the substituents at the phenyl-ring.

As said before, it's definitely NOT 6-APB. But whatever it is, at least it looks reasonably pure.

Here's a quote from one of the official 5 sites that I sure hope the vendor will honor (because mine has already been dispatched):

"In the unlikely event that an item sent to you is found to be faulty, we will offer you a replacement."
 
threads merged.

people should remember that the analytical data supplied by vendors may or may not be a work of fiction and any resemblance to material available may be purely coincidental or whatever the standard hollywood disclaimer is

I am not going to bother looking at any analytical data unless it is from an independent and trustworthy source.

the vendors are dishonest shites.
