Tests for the presence of MDxx, DXM, 2C-B, speed and more. The Marquis Reagent is a mixture of concentrated sulfuric acid and formaldehyde. The Marquis reagent is a very good field test for a wide variety of substances and can be used in conjunction with our Simons reagent to tell the difference between MDA and MDMA/MDEA, or between methamphetamine and amphetamine, or between MDPV and methylone. Remember these tests work by identifying the presence of a substance so using more than one test can help you narrow down precisely what substances can be identified. Don't worry if that is confusing, each kit includes a detailed instruction manual.
