Set 1: Beta ketones.
There was a bit of a mess at the top - my apologies.
Naphyrone
Marquis - yellow
Mecke - no reaction (kept the brownish color it had out of bottle)
Mandellin - Clear
No fizz.
Mephedrone
Marquis - no color change, some fizz
Mandellin - stayed yellow (that's the one visible to the left of Mandellin column)
Mecke - no reaction (kept the brownish color it had out of the bottle)
MDPV, Methylone, Butylone:
Marquis - yellow
Mecke - red-brown
Mandellin - clear
Fizz from all reagents.
Buphedrone, Ethcathinone, 3 and 4 Flouromethcathinone:
Marquis - no reaction
Mecke - slight brown, almost no change.
Mandellin - slight browning.
Fizz from all reagents.
Set 2 - Other stimulants and empathogens:
Notes:
Desoxypipiradrol
Marquis - brown
Mecke - brown
Mandellin - yellow/brown
Some fizz, slow reactions, weak colors.
6-APB
RESULTS REMOVED
IDENTITY OF CHEMICAL TESTED HAS BEEN CALLED INTO QUESTION.
5-IAI
Marquis - orange-brown
Mecke - light brown (note in above, obscured by 6-APB test running into it)
Mandellin - brown
Slow reactions, no fizz
MDAI
Marquis - red/orange for mostly-clean freebase, brown-black (hard to see in pic) for tan HCl salt.
Mecke -
Mandellin -
Tan HCl fizzed, white base did not
2-Aminoindane
Marquis - no reaction
Mecke - brown
Mandellin - light blue
Vigorous fizz from all reagents.
Amphetamine
Sample from Adderal XR, lack of results may have been due to small/impure sample. No color change with any reagent.
Ephedrine
Sample from BOLT brand single constituant ephedrine pills.
Marquis - no reaction
Mecke - no reaction
Mandellin - yellow-orange
Caffeine (anhydrous, USP)
Marquis - no reaction
Mecke - slight browning
Mandellin - no change
Key points to take away:
These reagents are not sufficient for differentiation between cathinones of similar structure.
These reagents are not sufficient to confidently confirm presence of mephedrone.
These reagents are not sufficient to confidently rule out the presence of most cathinones in combination with other agents that produce strong colors.
These reagents are not sufficient to confirm or rule out presence of desoxypipiradrol in combination with other agents, especially as the active dose is very low. Luckily I am not aware of this horrible drug showing up as an adulterant.
MDAI on the market is so filthy that the impurities confound identification with the marquis reagent.
2-AI, which many people have reported dangerous reactions from, can be confidently detected using the mandellin reagent.
I hope this is useful to people who may be in the situation of having to identify something which may contain research chemicals. I intend to do similar tests with synthetic cannabinoids, psychedelics, and sedatives.
Phenethylamine Psychedelics, by popular demand (despite that most of these come from reputable vendors, not sketchy products)
All of these fizz on contact with reagent.
2-3 minutes after testing:
~30 minutes after testing
2C-C:
Marquis - yellow, changing to light green, and then fading over time
Mecke - yellow/brown/green, green fades over time
Mandellin - clear
2C-B:
Marquis - yellow, changing to green, and then fading over time
Mecke - yellow/brown
Mandellin - yellow fading to clear
2C-I:
Marquis - Green-blue with yellow edges, fades to blue, fades over time
Mecke - dark brown, very fast
Mandellin - clear
2C-D:
Marquis - Very faint brown, fading to clear.
Mecke - Yellow-brown fading to reddish brown
Mandellin - Yellow w/tinge of green fades to clear over time
2C-E:
Marquis - Very faint brown, fading to clear.
Mecke - Dark brown
Mandellin - Yellow w/tinge of green fades to clear over time
2C-P:
Marquis - Very faint brown, fading to clear.
Mecke - Yellow-brown fading to Rusty Brown
Mandellin - Yellow w/tinge of green fades to clear over time
Slow reactions.
2C-T-2:
Marquis - Almost no reaction, slight brown.
Mecke - Black fading to rusty red.
Mandellin - Red fading to clear over time
Key points:
These reagents are suitable for identifying 4-halo 2C's; differentiation between them is possible but difficult.
These reagents are suitable for identifying 4-alkyl 2C's; differentiation between them is not realistically possible.
These reagents are excellent for identifying 4-thioalkyl 2C's. As only 1 thioalkyl 2C was available, nothing can be said for differentiation between 4-thioalkyl 2C's.
I am unable to replicate results indicating that 2C-E produces a green or yellow color, yet these chemicals are known good, and produce effects that are in every way consistent with expectations, including the characteristic durations and dosages for 2C-D/E/P.
