How can I tell if it's amphetamines?

Drugtest, heat some of it to the desired temperature (it will melt and burn)

no, he use it for extraction but ether is compatible with the GAA?
I think problem is that the GAA is the solvent ...
And don*t forget the exothermic reaction with NaOH :D

Thank you for your answer. This damn translator always makes us wrong. What kind of reagent is GAA? Glacial acetic acid?

Hello, it is said that there is an extraction procedure. EA here is used as extractant (solvent) for extraction of oxime.

Hello, thread creator, there are a few questions I would like to answer. 1 Is it necessary to evaporate ethyl acetate after using ethyl acetate extraction? 2 Is it okay to use 37% hydrochloric acid without water? 3 What is the PH value after adding sour water? 4 Can small particles of zinc be used without zinc powder?

From 7.5 grams of p2np I obtained 4 grams of amphetamine. Is it good?

A good way to test the validity/purity of a compound is to test it with a reagent chemical:

marquis is often one of the ways of testing amphetamine:
look up dancesafe for example, or 'reagent tests'

what was the concentration of the acid you used to precipitate the amphetamine at the end?

How do you have such a precise measurement? Did you have it tested with gas chromatography?

ok. i was asking about the purity of the amphetamine just before, so perhaps I should have touched on that. @tucosalamanca, have you definitely got pure amphetamine? mine is extremely contaminated as it has been with other methods :(

I have pure amphetamine, my first synthesis was dirty, my second synthesis was pure.

I don't have access to concentrated sulfuric acid where I am. If you have it could you try to precipitate the amphetamine with 85% phosphoric acid and see how pure your end product is?

I have no idea why the synthesis keeps failing for me, but I think the 85% phosphoric acid I'm using is the only thing that remains the same throughout all of my synthesis attempts.

Thank for any help :)

Thats ok. But the thread opener wrote: 90% of 15g are 13,5g

So you need: 6,75g
