Bacteria that can grow on this medium producean enzyme, citrate-permease, capable of convertingcitrate to pyruvate. R. L. Courtney and S. F. Duliere, Carbon London Negative test (i.e. Methylone, a drug thats one of the more common drugs sold as molly, will turn a bright yellow color. It also acts as a good negative control for amphetamines, since it should not react with them. jmolApplet = Jmol.getApplet("jmolApplet0", NInfo); What it tests for is the presence of a secondary amine group (which is a nitrogen that has two carbons attached.) Sodium Chloride maintains the osmotic balance of the medium. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Mail Us:WIM SCIENTIFIC LABORATORIES3157 Farnam StreetSuite 7104PMB7149Omaha, NE 68131, Copyright 2023 WIM Scientific Laboratories LLC, Be the first to review Simons A/B Reagent. 0000009197 00000 n Pay $10 each when you buy 30 or more. Pay $12.50 each when you buy ten or more. The Simon's reagent is then used to differentiate between MDMA and the closely related compounds MDA and MDE. When exposed to an amine, reaction with acetaldehyde produces the enamine, which subsequently reacts with sodium nitroprusside to the imine. NOTE: Simon's can only test the PRESENCE, not PURITY or QUANTITY of a specific substance. Are you a retail or online store, hospital, pharmacy or public health agency?
