Key points to take away:
These reagents are not sufficient for differentiation between cathinones of similar structure.
These reagents are not sufficient for detection or identification of 4-FA or pipirazines, nor weak OTC stimulants - though 4-FA will test positive with robadope.
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. Sniff test and Simons may be helpful here.
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.
2-AI, which many people have reported dangerous reactions from, stands out like a sore thumb when tested with the mandellin reagent.
There is more fake 6-APB than real 6-APB on the market.
MDAI on the market is so filthy that the impurities confound identification with the marquis reagent.
All of these should be positive to Robadope and negative to Simons.
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; differentiation between them is not practical without reference samples.
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.
Set 4: Tryptamines:
These reagents are sufficient for detecting tryptamines.
These reagents are sufficient for narrowing the range of possible tryptamines, but not for positive identification.
Mecke turns reddish brown in the presence of 5-MeO-T's, and brown in the presence of 4-HO/4-AcO-T's.
These reagents are not sufficient to detect 4-MeO-PCP.
These reagents are sufficient to detect synthetic cannabinoids in common circulation
These reagents are sufficient to distinguish between classes of synthetic cannabinoids, but not between closely related compounds.
It is as yet unverified whether these are suitable for analysis of smoke blends, or determination of adulterants in cannabis.
ein nützlicher test um ephedrine und cathinone nachzuweisen ist die chen-kao reagenz.
lässt sich sehr simpel herstellen aus baumarktchemikalien, kupfersulfat ist in unkrautvernichtungsmitteln o.ä. drin. chen kao reaktion, wikipedia
