Links checked and/or last Magnesium Sulfate is a cofactor for a variety of metabolic reactions. The Simons Reagent kit is a secondary test (after the use of Marquis, Mecke, & Mandelin) that tells the difference between MDMA vs MDA, methamphetamine vs amphetamine, or between MDPV vs methylone. Find the best reagent test kits HERE. [CDATA[ This includes the cathinones and presumably K-2C-x compounds. On a clean ceramic surface (e.g. Preparation of Benedict's Reagent.

DoseTest is here to shake up the harm reduction world, taking lifesaving materials like reagent test kits and fentanyl test strips from the small niche where they have lived and making them accessible to everyone. Using the test tube place one drop of RobaTest reagent and then 2 of buffer and swirl gently (to mix) and wait 30 to 60 seconds and note the colour. Colour Test Reagents/Kits for Preliminary 0000047097 00000 n The primary use of this reagent is for detecting secondary amines, such as MDMA and methamphetamine, and is typically used after the mecke or marquis reagents to differentiate between the two mentioned and amphetamine or MDA. Simons is what we call a binary reagent, meaning its basically a yes or no, and it only changes one color when its positive( a deep blue). 0000126029 00000 n . Color test reagent formulations are summarised in Table 2. Subscribe and get 10% off your first order.

[1], The reagent is typically provided in two parts:[2][1][3]. Simon's reagent is composed of an aqueous mixture of sodium nitroprusside, sodium carbonate and acetaldehyde, which is dripped onto the substance being tested. Bacteriological agar is thesolidifying agent. In the early 1920s, Koser developed a liquid medium formulation for the differentiation of fecal coliforms from the coliform group. 0000159563 00000 n and those who inject drugs. The test is often used to distinguish ephedrine, pseudoephedrine, norephedrine, cathinone and methcathinone from amphetamine and methamphetamine, Finally, the immonium salt is hydrolysed to the bright cobalt-blue Simon . Your email address will not be published. 2 10ml of USA factory sealed ISO 9001 Quality Lab Material Certified Dropper bottles. This is why multiple tests are recommended when testing a compound, because the more reagents you use, your confidence increase since you reduce the risk of a false positive. Acumedia Manufacturers, Inc.-SIMMONS CITRATE AGAR (7156). Simmons later modified this formulation to produce a solid medium that eliminated potential errors when interpreting growth. I would like to go through test-by-test and describe our personal recommendations for molly testing reagents and explain why we recommend each. Upon shaking with ether, the organic phase turns red/purple and the aqueous phase turns blue. Replace the cap. When exposed to an amine, reaction with acetaldehyde produces the enamine, which subsequently reacts with sodium nitroprusside to the imine. Instructions, safe handling, storage and most importantly reactions charts. Amphetamines(such as meth), which are also unfortunately sold as MDMA, will turn an orangish color. S. tani, A. ya and J.

To estimate purity of a substance (amount of adulterants and potency) use. L. L. Ban, D. Crawford and H. Marsh, J. Appl. It reacts with secondary amines like MDMA and methamphetamine to give a blue solution. Mandelin is particularly useful for testing molly samples, because its able to detect a potential deadly adulterant that is now rarely(thankfully) sold as MDMA. 27 October 2020. So every drug that Simons reacts with will theoretically have a secondary amine group. 0000005043 00000 n 0000001811 00000 n Edit: simons reagent is sodium nitroprusside 1 g in 50 ml distilled water; add 2 ml acetaldehyde So this is completely different than marquis reagent, which is 100 ml concentrated sulfuric acid added to 5 ml 40% formaldehyde. The procedure is as follows: Place small amount of material to be tested on a spot plate. The execution of the Chen-Kao reaction is simple, needs little practice and limited skills. It is mandatory to procure user consent prior to running these cookies on your website.

A. Oberlin, M. Oberlin and J. R. Comte Trotet, J. Microsc. Electron In order to further differentiate between ephedrine enantiomers - ephedrine, pseudoephedrine and other ephedrine-related compounds, Simons test (with acetaldehyde) and Simons test (with acetone) are used. This website uses cookies to adjust and correctly display content. The Simmons-Smith reaction involves the reaction of diiodomethane, a zinc-copper couple and alkenes to give cyclopropanes (Equation (14) ). United Nations, New York, NY. These were excellent and worked very precisely seeing I have no previous lab skills. 1520 0 obj <> endobj Tubes should be stored in a refrigerator to ensure a shelf life of 6 to 8 weeks. The Simons Reagent kit is a secondary test (after the use of Marquis, Mecke, & Mandelin) that tells the difference between MDMA vs MDA, methamphetamine vs amphetamine, or between MDPV vs methylone.

What makes testing MDA tricky, is the fact that it has the same exact reactions as MDMA for marquis, mecke, AND mandelin. No reaction within the first 30 seconds or unexpected results indicate the sample doesnt contain the expected substance or is adulterated. Dipotassium Phosphate actsas a buffer. Flush the reaction in a sink under running water. 0000125387 00000 n These faster rates are associated with lower activation energies. Separate storage of the aldehyde and base are necessary to prevent aldol polymerisation of the aldehyde. [3][5], Acetaldehyde can be replaced with acetone, in which case the reagent detects primary amines instead, giving a purple coloured product.[3]. So every drug that Simon's reacts with will theoretically have a secondary amine group. 0000047604 00000 n More info. 0000009197 00000 n citrate utilisation) produces an alkaline reaction and changes the color of the medium from green to bright blue.Examples:Serratia and the majority of the Enterobacter, Citrobacter, Klebsiella, Proteus and Providencia species, except Morganella morganii and Klebsiella rhinoscleromatis. 17 (1979) 131.

Kovar, 0000213720 00000 n A drop from each solution (A and B) is dripped onto the substance being tested, causing the two solutions to mix together. 0000005226 00000 n If no color change is observed when solution B is added, then the substance contains MDA, amphetamine, or MDPV. Well one of the classic precursors in MDMA synthesis is safrole oil. 17 (1979) 71.

It is one of three reagents in the MDMA kit. It reacts with secondary amines like MDMA and methamphetamine to give a blue solution. PreparePrepare a tiny bit of your drug on a white ceramic plate or mug.Tip: You should use the same amount of powder as on a matchstick head, or a grain of rice. Message Us With Any Questions Dismiss, THE ULTIMATE 2022 FESTIVAL SURVIVAL GUIDE, Marquis reagent: How does it work and why is it useful for testing drugs. If those impurities are active I don't know, but the reaction is so faint I think it will be just trace amounts of whatever is causing it. As this precursor became harder to find, its possible that unscrupulous precursor vendors sold fennel oil, which smells similar to safrole oil, to black-market labs looking to synthesize MDMA. Anyone you share the following link with will be able to read this content: Sorry, a shareable link is not currently available for this article. Growth; color change of medium to blueNegative control:Escherichia coli ATCC 25922. A characteristic blue coloration appears when the test is positive. They can detect all adulterants at once, but still require reagent tests for identifying ingredients. This is a preview of subscription content, access via your institution. Always test under a strong light and using the smallest possible sample. Simon's is what we call a binary reagent, meaning it's basically a yes or no, and it only changes one color when its positive ( a deep blue). Cool in slanted position (long slant, shallow butt). Chem. "Die gegrillte Leber ist super" 1520 52 Uses. R. L. Courtney and S. F.

Adair, Carbon You also have the option to opt-out of these cookies. This precipitate could be seen as characteristic for the members of the ephedrine group other than pseudoephedrine and ephedrine itself, hence, the Chen-Kao test appears to show a significant specificity within the ephedrine group. A variation of this reaction is the Furukawa cyclopropanation reaction, 143 which involves the treatment of alkenes with diethylzinc and diiodomethane. 1 (1976) 391. Crystallogr. It also acts as a good negative control for amphetamines, since it should not react with them. We have already described in another post, the chemistry behind why exactly marquis reagent works, but in short, it reacts with nitrogen groups in a compound to produce a specific color for each drug.
