M. Nakamizo, M. Inagaki, H. Kakiyama and H. Honda, ibid. 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. Dille-Kopanyi Solutions 1 and 2 were from a testing kit produced by nik Public Safety. 53 (1970) 1126.

High Press. 0 Comments (see Table III)[4], When acidic solution of ephedrine or pseudoephedrine is mixed with copper sulfate and sodium hydroxide solutions, a violet color is formed. Rates of oxidation with mixed acid increase G. When exposed to an amine, reaction with acetaldehyde produces the enamine, which subsequently reacts with sodium nitroprusside to the imine. Deionized water =1,000 mlFinal pH 6.9 +/- 0.2 at 25 degrees C. Simmons Citrate agar is used to test an organismsability to utilize citrate as a source of energy. When exposed to an amine, reaction . Upon shaking with ether, the organic phase turns red/purple and the aqueous phase turns blue. forensic science services, SCIENTIFIC
