Simon's reagent

Simon's reagent is used as a simple spot-test to presumptively identify alkaloids as well as other compounds. It reacts with secondary amines like MDMA and methamphetamine to give a blue solution.


Uses edit

The primary use of this reagent is for detecting secondary amines, such as MDMA and methamphetamine, and is typically used after the mecke or marquis reagents to differentiate between the two mentioned and amphetamine or MDA.[1]

Chemistry edit

The reagent is typically provided in two parts:[2][1][3]

Separate storage of the aldehyde and base are necessary to prevent aldol polymerisation of the aldehyde.

When exposed to an amine, reaction with acetaldehyde produces the enamine, which subsequently reacts with sodium nitroprusside to the imine. Finally, the iminium salt is hydrolysed to the bright blue[1] Simon-Awe complex.[3][5]

Acetaldehyde can be replaced with acetone, in which case the reagent detects primary amines instead, giving a purple coloured product.[3]

Testing Method edit

A drop from each solution (A and B) is dripped onto the substance being tested, causing the two solutions to mix together.
