2C-B Reagent Test (1 test)
How to test?
2C-B Reagent Test includes Marquis reagent best for 2C-B. MDMA, MDA or meth/amphetamine but also suitable for benzofurans, cathinones, opioids and more. It is used to positively identify 2C-B/C/H/I, MDMA, MDA, meth/amphetamines, 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 PURITY or 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.
The 2C-B Reagent Test includes Marquis reagent, micro spatula, instructions and app for all test kits and over 700 substances. Each ampoule contains enough reagent for at least 1 test. Oxygen-free hermetically sealed glass ampoule protects reagent from light, plastic and moisture to ensure prolonged shelf life.
PRO 2C-B Reagent Test is best for 2C-B, MDMA, MDA or meth/amphetamine but it’s also suitable for benzofurans, cathinones and opioids.
To compare reagents see the chart below. ➕➕ = positively indicates presence of expected substance. At least 2 are recommended to reduce the risk of inconclusive result. ➕ = positively indicates presence of some adulterants (see footnotes). ➖ = not applicable.

- Cannabis (4-AP) – main test for THC / CBD, helps rule out synthetic cannabinoids
- Ehrlich – main test for all indoles, e.g. lysergamides and tryptamines but also 5-HTP and more, secondary test for cocaine
- Hofmann – main test for lysergamides and tryptamines, more precise but slower than Ehrlich
- Froehde – main test for most powders, secondary test for ketamine and amphetamines, long shelf life
- Liebermann – main test for most powders, secondary test for cocaine (detects levamisole)
- Marquis – main test for most powders, secondary test for ketamine, mephedrone and psychedelics
- Mecke – main test for most powders, secondary test for cocaine, ketamine and mephedrone
- Morris – main test for cocaine and ketamine, can tell apart some novel dissociatives
- Robadope – main test for primary amines, e.g. MDA, amphetamine or PMA
- Simon – main test for secondary amines, e.g. MDMA, meth, mephedrone, methylone or PMMA
- Zimmermann / Beam – main test for cathinones and benzodiazepines in geneal, detects also CBD
Fentanyl Test Strip to detect fentanyl, even if it is mixed in another substance.
Reagents can indicate PRESENCE, but not PURITY or QUANTITY. Adulterants can be detected with reagents only if they cause a darker color change than the expected substance. To detect all ingredients and estimate their amount pair reagents with a TLC purity test kit.
GET ALL TOOLS
Get your sample, reagent ampoule, a sharp tool / scoop and paper towels.
PREPARE SAMPLE, ABOUT THIS BIG -> ●
If testing a pill, powder or crystal, crush it finely. If testing a liquid, dry one drop on paper or clean ceramic surface. A bigger sample can cause a stronger reaction. You need a new sample for each test.
ADD PREPARED SAMPLE TO REAGENT
Break open glass ampoule by gently pushing bottom of plastic cap outwards with your thumb pointing down. Do not crush the glass ampoule, after a few soft pushes and 10-20 seconds of trying the ampoule head will snap off without any effort. Using included plastic spatula add prepared small (●) sample inside opened glass ampoule.
OBSERVE FOR UP TO 3 MINUTES
Disregard any color change after 3 minutes. Do not overinterpret your results, consider that color change reaction is always fastest and most vivid in the part where biggest surface of reagent touches sample, compared to its edges. Over time reaction will degrade due to air contact. Take photos.
Compare color change with instructions. Reagents can indicate PRESENCE, but not PURITY or QUANTITY. Adulterants can be detected with reagents only if they cause a darker color change than the expected substance. To detect all ingredients and estimate their amount pair reagents with a TLC purity test kit.
Close used items inside plastic tube and dispose safely.
Expected Marquis reagent test results:
- 2C-B – yellow > green > blue
- Cathinones – yellow
- Caffeine – no color change
- Cocaine – no color change / peach / pink
- Ketamine – no color change
- MDMA – instant black
- Meth/amphetamine – orange > brown

Reagents contain toxic and/or corrosive chemicals, strong enough to burn skin and clothing. Keep out of eyes and mouth. Keep away from children and animals. Always use in a well-ventilated area. Wear gloves and protective eyewear. Never point towards face etc. If you get some on you/clothing, then immediately wash with lots of soap and water. Dispose of any unwanted reagent with running water, ventilate. Store reagents standing up and away from heat in a cool, dark place.
Reagents deteriorate with time or due to contact with air, especially if exposed to sunlight or not refrigerated. If you are uncertain whether the reagent will work, test it with an already confirmed sample.
Pair reagents with a TLC purity test kit. TLC allows you to discover full number of ingredients and estimate their amount, however still requires reagent tests to identify detected compounds.
- To precisely test MDMA purity use TLC MDMA Purity Test Kit.
- To precisely test cocaine purity use TLC Cocaine Purity Test Kit.
- To precisely test cannabinoids use TLC Cannabinoid Test Kit.
- To estimate purity of other compounds (full ingredients and their amounts) use the basic TLC Adulterants Test Kit.
- To precisely test purity of as many compounds as possible consider the Full TLC Purity Test Kit.
