OMPP in complressed plant? material
ORTHO-METHOXYPHENYLPIPERAZINE (OMPP) IN SEABROOK, TEXAS The Pasadena Regional Crime Laboratory (Texas) recently received a two-exhibit submission including about 0.5 grams of cocaine and 0.8 grams of a compressed green material, similar in appearance to an animal food pellet, submitted as suspected to contain MDMA (see Photo 5). The exhibits were seized by the Seabrook Police Department, pursuant to a traffic stop in Seabrook. A preliminary screen of the second exhibit using ferricyanide indicated the presence of a secondary amine, but the color change was slower than would be expected for MDMA. All other spot tests (including Marquis) were negative (suggesting MDMA was not present). Analysis by GC/MS, FTIR, and UV indicated not MDMA but rather 1-(2-methoxyphenyl)-piperazine (OMPP; not confirmed due to the lack of an authenticated standard). The exhibit was not quantitated, but the OMPP loading was low based on the TIC. This was the laboratory’s first encounter with a piperazine in any form.
