Hirose, Fuel Simon's reagent is used as a simple spot-test to presumptively identify alkaloids as well as other compounds. This modification is not included in the UN Precursor Test Kit and other spot tests alike. Get the latest business insights from Dun & Bradstreet. The Chen-Kao test is performed by creating an acidic solution of the compound to be tested and adding dilute Copper (II) Sulfate and Sodium hydroxide solutions.The procedure is as follows: Further, the coordination complex might be extracted with organic solvent like diethyl Ether or n-butanol (see Table II), as proposed in the literature,[8][9] which provides additional confirmation of the original results, but no further differentiation. 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. Part of Springer Nature. If the sample consists of MDA, 5-APB, 6-APB, it won't change color. Add 2 drops of reagent A Add 2 drops of reagent B Add 2 drops of reagent C A violet color indicates presence of ephedrine or pseudoephedrine Reagent A - 1% (vol/vol) aqueous acetic acid solution Reagent B - dissolve 1g Copper (II) sulfate in 100ml water This website uses cookies to adjust and correctly display content.

Ingredients per liter of deionized water:*. 11 (1973) 289. The staining is based on the formation of a coordination complex of two ephedrine molecules and a copper ion Cu2+[4][10], This works, because, in an alkaline solution, the hydroxyl and amine groups are de-protonated, leaving a negative charge on the central atoms.

One litre of Benedict's reagent can be prepared by mixing 17.3 grams of copper sulfate pentahydrate (CuSO 4 .5H 2 O), 100 grams of sodium carbonate (Na 2 CO 3 ), and 173 grams of sodium citrate in distilled water (required quantity). Unlike other Simons A/B Reagent Providers we provide you with everything you need to identify illicit substances and compounds. The reagent is typically provided in two parts: [2] [1] [3] A mixture of 2% sodium nitroprusside and 2% acetaldehyde in water (solution A) [4] A solution of 2% sodium carbonate in water (solution B) [4] Separate storage of the aldehyde and base are necessary to prevent aldol polymerisation of the aldehyde. They can then form a coordination complex with the positively-charged cupric ions from the copper sulfate. 0000008240 00000 n
The oxidation was carried out in the apparatus shown in Fig. However, in cases of doubts, they may serve as confirmatory steps.

However, it is known from previously published cross-testing work that various pharmaceuticals not related to the ephedrine group may produce similar blue copper complexes. Flush the reaction in a sink under running water. Starting from the basics, reagent testing kits are chemical mixtures that react with a given compound(drug) such as MDMA, and produce a predictable color when they come in contact with that drug. 83 (1975) 70.
