GUIDE How to test 2C-B?
How to test 2C-B: if you intend to use a psychoactive substance first you need a test kit to check purity. Pure 2C-B can look brown or tan and can’t be identified by appearence. Check your sample with a single or multi-use 2C-B test kit.

Recommended 2C-B testing kits
Recommended multi-use 2C-B reagent test kit includes reagents Marquis, Mecke, Simon’s, Robadope and Zimmermann. Reagents Marquis, Mecke, Robadope are required to identify 2C-B. Simon’s reagent helps detect CMC, MMC, methamphetamine, MDMA or PMMA. Zimmermann reagent helps detect benzodiazepines and cathinones. To discover full ingredients and estimate 2C-B % pair reagents with TLC MDMA Purity Test Kit. To detect fentanyl use the fentanyl test strips.

What are 2C-B test kit reagents used for?
| SAMPLE | RECOMMENDED 2C-B REAGENT TESTS |
| 2C-B / MDA / MDMA / METH/AMPHETAMINE |
Reagent tests indicate presence of a substance, therefore can either help confirm presence of the expected compound or help rule out certain cuts.
- 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
- Simon – main test for secondary amines, e.g. MDMA, meth, mephedrone, methylone or PMMA
- Robadope – main test for primary amines, e.g. 2C-B, MDA, amphetamine or PMA
- Zimmermann / Beam – main test for cathinones and benzodiazepines in geneal, detects also CBD
- Single use 2C-B test kit includes Marquis reagent
- Multi use 2C-B reagent test kit includes reagents Marquis, Mecke, Simon’s, Robadope and Zimmermann
Marquis reagent is the main test for 2C-B and produces a yellow-green color change with 2C compounds. Mecke reagent and Robadope are the recommended follow up tests.
Simon’s can detect secondary amines (meth, MDMA, PMMA, mephedrone derrivatives) in MDA. Zimmermann reagent helps rule out secondary and tertiary cathinones, mostly MMC and PVP analogs.

2C-B drug test: 2C-B vs Tuci (“pink cocaine”)
2C-B and Tuci are completely different drugs, although they share a similar name. 2C-B is a psychedelic phenethylamine, characterized by very low “head space” and strong visuals. Tuci on the other hand is what we call “trash off dealer’s table”, usually a random mixture of pink food coloring, ketamine, MDMA and caffeine, but the full list is much longer (source: https://www.unodc.org/documents/scientific/Global_SMART_Update_2022_Vol.27.pdf)
STEP TWO How to test 2C-B purity %?
To discover all adulterants and estimate quantity pair reagent tests with a TLC (Thin Layer Chromatography) Purity Test Kit. TLC purity tests alone don’t identify substances and are best paired with at least 1-2 reagent tests. Thin Layer Chromatography is one of classic substance analysis methods. It works by separating different compounds depending on their solubility in chosen TLC testing liquid (eluent). To precisly estimate 2C-B purity pair a reagent test kit with the MDMA Purity Test Kit which works for a variety of compounds.
How to test quality of 2C-B?
Qualitative TLC:
TLC test works by separating substances present in a sample, each detected spot indicates a different substance.
- You can use an already confirmed sample for reference – if both compounds show up at the same height on the TLC “card” that indicates they can be the same substance.
- You can use any substance for reference after establishing their relation – if substance X shows up twice as high on the same testing “card” as substance Y, you can expect them to keep that ratio.

How to test quality of 2C-B?
Semi-quantitative TLC:
TLC helps estimate quantity (potency). The bigger the size of the detected spot, the bigger the amount of measured substance. Note that different substances need different calibrated rulers and often different testing liquids (eluents).
- One spot indicates a pure substance. If your sample fully dissolved in testing liquid and only one spot was detected on TLC then your substance is pure. Trace amounts of impurities might not be detected, do not rely on TLC for fentanyl testing – get also fentanyl test strips.
How to use TLC purity tests?
How to test 2C-B for fentanyl?
Use fentanyl test strips (a fentanyl test kit)
METHOD 1
If testing a benzo/opioid pill, crush one in a plastic baggie and dump out the powder. Then add 10 drops of water into the baggie and mix well. Dip the test strip no higher than the thick line. Wait 15 seconds. Put the strip away and check in 5 minutes.
METHOD 2
Mix 100 mg of sample in 200 ml of water. Dip the test strip no higher than the thick line. Wait 15 seconds. Put the strip away and check in 5 minutes.
COMPARE RESULTS
1 line = fentanyl, 2 lines = no fentanyl. Faint lines also count. Ignore fentanyl tester results after 5 minutes.
To detect all ingredients and estimate their amount pair reagents with a TLC purity test kit.
A positive or negative test result does not indicate if a substance is safe. No substance is 100% safe.
