ppma PHENYLPROPYLMETHYLAMINE botched chemistry

- INTELLIGENCE ALERT - PHENYLPROPYLMETHYLAMINE IN BROWARD COUNTY, FLORIDA The DEA Southeast Laboratory (Miami, Florida) recently received a small amount of yellow powder, submitted as an unknown, suspected designer drug (see Photo 1). The exhibit was submitted by the Broward County Sheriff's Office Crime Laboratory, and was taken from a 633 gram seizure previously submitted to that laboratory (details of seizure not provided). The powder did not give a color change with either the Scott's test or Mecke reagent; however, a slow orange color developed with the Marquis reagent, and a deep blue color was observed with sodium nitroprusside. Analysis by GC/MS on both a chloroform extract (from a basified solution) and the TPC derivative, and by FTIR and NMR, indicated racemic phenylpropylmethylamine (PPMA) hydrochloride (quantitation not performed). This is believed to be the first ever submission of PPMA HCl to the Southeast Laboratory. [Editor’s Notes: PPMA is the “mistake” product from the use of an incorrect precursor in illicit “prop-dope” methamphetamine laboratories (that is, 2-phenylpropanal instead of phenyl-2-propanone), and has been occasionally reported to Microgram since 1982. It has minimal (if any) CNS stimulant activity, and is not controlled. A comprehensive analytical profile of PPMA was published in Microgram 1998;31(10):269. Note that all issues of Microgram prior to January 2003 are law enforcement restricted.]
