    If your sample turns out to be MDA, you would have a color black or purple solution instead of a clear and colorless one. it should take around five seconds to do so and you have to note that there may be some dark purple tints in the solution.


    For amphetamine and methamphetamine, the color would range from orange to dark brown. It may also have some brown tint as well. You would see this result on about zero to five seconds after you have dropped your Marquis reagent to your compound.


    For 2C-B the color is quite distinct so you would not mistake it with another one. You should have a yellow to green colored solution after adding the Marquis reagent in your compound of interest and it should appear there after five to ten seconds. There color may eventually change from your original results but it is going to be quite something for sure.


    For this substance, you should be able to get a gray color to a black color within fifteen to thirty seconds after dropping your reagent. Initially there would be no change so you can easily differentiate it with MDA. Make sure to note the reaction time so that you would not get confused at all.
