Amphetamine Reagent Test includes Marquis reagent best for meth/amphetamine, MDMA, MDA or 2C-B but also suitable for benzofurans, cathinones, opioids and more. It is used to positively identify meth/amphetamines, MDMA, MDA, 2C-B/C/H/I, 5-MAPB, 6-APB, 6-APDB and to rule out cathinones, DXM, PMA/PMMA, or different, less predictable, less desirable, highly toxic dangerous drugs. Multiple reagents are required to detect adulterants and increase analysis precision.
Reagent tests can indicate PRESENCE, but not QUANTITY. Mixtures can be detected with reagents only if adulterant causes a darker color change than the expected substance. To detect all ingredients and estimate their amount pair reagents with a TLC purity test kit.
