I checked and did not find info about.

How to convert 5-meo dmt fumarate to freebase.

Thanks,

You can do it in many ways, same as you'd do for DMT.. Check BLAB tek for some examples

Be well.

Makes perfect sense, thanks.

I wonder how much it degraded after 7 years

Under the correct storage conditions it should be stable indefinitely, notwithstanding a tiny amount of decomposition of carbon-14 if it's of organic origin.

That's good to hear.

Now I realize I used way too much water for the 0.25 Meo and added the prepped solution.

I will wait several days as advised in BLAB.

I am a bit rusty and need some direction.

How to recover now when nothing precipitates?

FASA ?

What exact method are you using? What have you done so far? Method 1, dissolving in water and basing with sodium carb? I should prob have advised to make a paste and pull with ipa but worst case scenario you pull your water with a non polar to retrieve your 5-MeO-DMT

Just dont throw anything away, it can always be recovered if something doesnt go as expected

This indeed

Dissolving in water and basing with sodium carb.

Ok, reteive with non polar.

then evap i guess ?

after that is it in salt or base form ?

if you based it, it will be in freebase form.

Yeah you can evap, or you can try freeze precipitating too.

Good luck, let us know how it goes

So in short.

It's a regular a/b approach.

First, bring PH up to up 12 then shake with polar & separate.

One last thing. Using DCM is ok?

Can I get a response?

Yes DCM is a good choice. Becareful as it can form emulsions quite easily. When you evaporate your DCM off you will get 5meodmt as an oil of unresolved polymoprhs. You will have to recrystallise

Also dont forget to be quick with DCM-handling.

It will react with Tryptamines over the course of hours to days and make them inactive.

The water with the dissolved MEO was about 100ml, added NAOH ph is +12.

I added maybe 10 or less ml DCM.

So far I only recovered 0.06 of the 0.25

Strange, I thought just a minimum of DCM would be enough. I mean that a little DCM can hold a lot of DMT so I thought it would be the same with MEO.
I magnetically stirred it quite well, and separation with the funnel was quite easy and fast.

Seems I have to go for another round.

seems like the job is done.

3 pulls. left to right.

1. 0.06
2 0.1
3 0.02

Total 0.18 gr of the 0.25

Was this measured as 0.25g of the fumarate? Especially if it's the bifumarate, you won't recover the whole of the mass because the fumarate gets left behind. Some arithmetic will instruct you as regards your maximum possible yield.

Was this measured as 0.25g of the fumarate? YES

lab 5-MEO that I converted to fumarate and now back to base.

So, just to be absolutely clear, you converted 5-MeODMT to the (or a) fumarate and had 250mg (or 0.25g) of product which was then converted back to freebase, 0.18g being recovered.

Have you tried calculating how much fumarate would be formed from 0.18g 5MeODMT freebase?

That's way above my knowledge level!

But what do you think, is it a-ok result that I got?

Id imagine you are good to go, if your original product was indeed 5-MeO-DMT.

Good luck and let us know how it goes if you bioassay it.

Did you try 5-MeO-DMT before?

No, it is simple arithmetic and it would be very helpful to you if you were able to convert mathematically between the amount of fumarate and the amount of freebase. Fortunately, a dedicated Nexian produced a calculation tool, which I have now added to my sig for times like this

I'm not sure if it includes an entry for 5-MeODMT [EDIT: it does!] but it certainly does for mescaline and DMT along with various organic acids, and the Github page details how other alkaloids can be added - all you need to know is their molecular weight and their combining equivalent.

Edit: I've checked with the calculator and if you got 0.18g of freebase 5-MeO-DMT from 0.25g of 2:1 fumarate, that's a 91% yield, which is pretty good. Is there any possibility your fumarate was hydrated or maybe contaminated with excess fumaric acid? Otherwise it seems it may be worth your while to see if you can recover a bit more product from your working material.
