The marquis reagent is the most popular reagent test, primarily used with MDMA but versatile enough that it can be used to identify a wide range of compounds.
2 mL is enough for 30-40 tests. The reagent lasts approximately 1 year when stored upright in a fridge.
It does not detect PMA or PMMA – you should use the froehde or liebermann reagents to cross-check unexpected results.
These reagents have a shelf life of 9-12 months when stored in the fridge. All our products are shipped in high quality glass bottles to reduce degradation from light, moisture and reactions with plastics which will shorten shelf lives. After removing from the fridge make sure you let the reagent warm up and dry off before opening the lid.
Includes reaction result guide for common compounds.
