), however one other important drug we didnt mention is MDA (also known as sass or sassafras). However, a slow transition of the initial color into yellow, followed by an orange-brown color can be observed with both compounds, thus indicating the instability of the complexes initially formed, and an obvious decomposition of the two compounds under the alkaline conditions of this color reaction. 1 (1976) 391. 0000002020 00000 n

When exposed to an amine, reaction with acetaldehyde produces the enamine, which subsequently reacts with sodium nitroprusside to the imine. 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).

So, if marquis turned orange, and mecke doesnt change color at all, you have another confirmation that you have some type of amphetamine instead of MDMA. Secondly use reagent bottle Sb. Japanese Journal of Toxicology and Environmental Health MASATOSHI SYOYAMA Amphetamines(such as meth), which are also unfortunately sold as MDMA, will turn an orangish color. //
