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). 1. . Sigma-Aldrich, Inc.-SIMMONS CITRATE AGAR (S3681). Once you have that baseline colour (~light pink) then add the substance to be tested. The oxidation was carried out in the apparatus shown in Fig. 2 10ml of USA factory sealed ISO 9001 Quality Lab Material Certified Dropper bottles. A variation of this reaction is the Furukawa cyclopropanation reaction, 143 which involves the treatment of alkenes with diethylzinc and diiodomethane. 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. - 86.105.14.23. No reaction within the first 30 seconds or unexpected results indicate the sample doesnt contain the expected substance or is adulterated. 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.

Four carbons, of heat treatment temperature 2800 C, were prepared from pure phenol formaldehyde resin (A-component), from this resin doped with nickel acetylacetonate (Ts-component), from a coal-tar pitch (Tp-component) and from the resin containing 30 wt% nickel particles (50 m) (G-component). The results of the solvent extractions, summarized in Table II appear to add little novelty to the results of the original Chen-Kao reactions. doi:10.1371/journal.pone.0069609.
