It may have a slightly more olive-green color before turning purple black, but its generally regarded that marquis,mecke and mandelin turn a similar color when testing pure MDMA within 60 seconds (a dark black), If your molly turns yellow with Mecke, you can have a strong suspicion that you may have been sold a bath salt like methylone or butylone, since these cathinones turn a yellowish collor with mecke, instead of olive-black like MDMA should. Edit: simons reagent is sodium nitroprusside 1 g in 50 ml distilled water; add 2 ml acetaldehyde So this is completely different than marquis reagent, which is 100 ml concentrated sulfuric acid added to 5 ml 40% formaldehyde.

This precipitate could be seen as characteristic for the members of the ephedrine group other than pseudoephedrine and ephedrine itself, hence, the Chen-Kao test appears to show a significant specificity within the ephedrine group. The Simmons-Smith reaction involves the reaction of diiodomethane, a zinc-copper couple and alkenes to give cyclopropanes (Equation (14) ).
