Rend. However, a slow transition of the initial color into yellow, followed by an orange-brown color can be observed with both compounds, thus indicating the instability of the complexes initially formed, and an obvious decomposition of the two compounds under the alkaline conditions of this color reaction. 1520 52 Some organisms are capable of growth on citrate and do not produce a color change. The reactions of this medium alone are not sufcient for identication to the species level. 109 (1977) 145. If the sample consists of MDA, 5-APB, 6-APB, it won't change color. Simmons later modified this formulation to produce a solid medium that eliminated potential errors when interpreting growth.

Well one of the classic precursors in MDMA synthesis is safrole oil. The results of the solvent extractions, summarized in Table II appear to add little novelty to the results of the original Chen-Kao reactions. A characteristic blue coloration appears when the test is positive. Marquis is probably the most popular of all drug testing reagents, as it reacts with a very broad range of drugs and compounds.

In both cases the surface of the medium is lightly inoculated by streaking and, where slopes are used, the butt of medium is inoculated by stabbing. What it tests for is the presence of a secondary amine group (which is a nitrogen that has two carbons attached.) Upon shaking with ether, the organic phase turns red/purple and the aqueous phase turns blue. 002 and L Precursor Chemicals of Amphetamine-Type Substances.
