Congress and the DEA responded with the implementation of controls on P2P precursor chemicals such as phenylacetic acid (and its salts and esters), acetic anhydride, benzyl cyanide, benzaldehyde, and nitroethane, all of which are controlled as listed chemicals The MIPs were prepared based on terpolymer copolymerization under acidic environmental conditions at room temperature and with a solvent eluting template, using ephedrine as the template, and melamin .

Australian clandestine drug laboratories are constantly utilising alternative methods to produce methamphetamine, in part as restrictions are placed by Government on, for example, chemicals such as phenyl-2-propanone (P2P) (in the early 1980s), or on pseudoephedrine-containing pharmaceuticals, from the mid-2000s In the same way the tests ascribed to Mecke, Reichard and Schneider-Weppen may be carried out with aqueous solutions containing 0 . Phenyl-2-nitropropene is a chemical compound with the chemical formula is C 9 H 9 NO 2 A production process for substituted phenylacetic acids or ester analogues thereof is disclosed .
