No reaction within the first 30 seconds or unexpected results indicate the sample doesnt contain the expected substance or is adulterated. Simon's reagent is a 2 part test, one part on its own is orange and the other colorless. As this precursor became harder to find, its possible that unscrupulous precursor vendors sold fennel oil, which smells similar to safrole oil, to black-market labs looking to synthesize MDMA.

They can detect all adulterants at once, but still require reagent tests for identifying ingredients. 83 (1975) 70. 109 (1977) 145. It's best to use Simon's reagent to test PMMA vs PMA, MDMA vs MDA, or meth/amphetamine, but it's also a good test for mephedrone and other secondary amines. Due to the nature of Robatest you need to add a little more than for most of the other reagents (Liebermann . When exposed to an amine, reaction with acetaldehyde produces the enamine, which subsequently reacts with sodium nitroprusside to the imine. 1994.

Kovar, The staining is based on the formation of a coordination complex of two ephedrine molecules and a copper ion Cu2+[4][10], This works, because, in an alkaline solution, the hydroxyl and amine groups are de-protonated, leaving a negative charge on the central atoms.

They must be used together for the reaction to work. The Simmons-Smith reaction involves the reaction of diiodomethane, a zinc-copper couple and alkenes to give cyclopropanes (Equation (14) ). And while PMA is rare in the US, was reported to be seen as recently as the year 2001 in a Mitsubishi pill sold as MDMA. To estimate purity of a substance (amount of adulterants and potency) use. Secondly Testkits are a legal product, and commonly used by harm reduction organizations. It is one of three reagents in the MDMA kit. 7 (1975) 563. 0000009197 00000 n Simons is what we call a binary reagent, meaning its basically a yes or no, and it only changes one color when its positive( a deep blue). Colour Test Reagents/Kits for Preliminary The Simon's reagent reacts preferentially with the more graphitic structures of the G-component unlike the Ts-component which appears to be structurally homogeneous. A characteristic blue coloration appears when the test is positive.
