What are the impurities of certain RCs?

[twentysix]

I am curious as to what the impurities... What else might might be in, for instance, a batch of 4-AcO-DMT, other than it?

 

[immad]

I got mine lab tested and it contained 4-AcO-DMT, psilocin, and two other unidentified chemicals. It seems very active.

4-aco-dmt, psilocin, n-acetyl-psilocin, n-acetyl-4-aco-dmt. glyoxylates, dimethylamine, & indoles if the chemists are lazy too.

This is a question I've often wondered about too. What about 4-FA or other fluoroamphetamines? How commonly used are heavy metals like mercury in RC production, and which chems would be most likely (theoretically) to contain them?

Off the top of my head there's not too many places for the introduction of "heavy metals".

Inorganic (heavy metals):
Chromium/selenium oxidations (epoxides, diols, ketones)
Mercury/aluminum amalgam for reduction (nitropropene to MDx usually)
Borohydride waste (borates, lithium/sodium salts)
Permangenate residue from oxidation of alcohols
I suppose depending on the drug there's the possiblity of Friedel-Crafts catalysts hanging around (lewis acids, AlCl3 is one common one)

Organic contaminants:
Cyano compounds used in PCP analog synthesis
Drug precursors (isosafrole ketone et cetera)
Side reaction products (diamines and such)

Pretty hard to quantify any of this without USP test methods. It also helps to know what synthetic process your stuff likely came from.

4-aco-dmt, psilocin, n-acetyl-psilocin, n-acetyl-4-aco-dmt. glyoxylates, dimethylamine, & indoles if the chemists are lazy too.

Where do you get this info from? From what synthetic route are you supposing this, or do you base your answer on analysis of actual products?

When using GC-MS, 4-HO-DMT is an artefact of 4-AcO-DMT analysis, it appears even if it wasn't present in the first place.

Has anyone ever tested impurities of 4-FA or 2-FMA? Or any RC halogenated amphetamine?

 

[sekio]

Most of the tryptmine impurities I've "guessed" from the syntheses in PiHKAL/TiHKAL and also the Erowid analysis of degraded 4-aco-det.

I would expect the impurities in fluoroamphetamines to resemble "normal" amphetmine impurities. There would also likely be a small percentage of iso-fluoro-amphetamines (3-FA as impurity in 4-FA)

But, it's very hard to tell accurately without a nice large sample size and a GC/MS-NMR one-two punch.

Do you think there may be any residual flourine or normal amphetamine in there?

 

[sekio]

It's very doubtful

The fluorine is not "added in" later, you start with it already attached to the phenyl ring, and it's not going to come off under most normal conditions.
