GLC QUANTITATION OF "1-PIPERIDINOCYCLOHEXANECARBONITRILE (PCC) IN ILLICIT PHENCYCLIDINE (PCP)

A GLC method is presented for quantitatlng 1-plperidlnocyclohexanecarbonitrlle (PCC) in Illicit preparations of phencyclidlne (PCP) using a 60-cm 3% OV-7 column, ambient In-Jection port temperature, and N-methyI-N-propyl-l-phenylcyclohexylamine (PCMP) as Internal standard. Seventy-two street samples were analyzed. The median (range) PCP content for tablets, capsules, powders, and miscellaneous forms was 3.9 mg (1.0-29.4), 3.1 mg (0.001-142), 11.2% w/w (0.003-100), and 22.9% (2.1-40.8), respectively. Twenty-two percent of the samples were contaminated with PCC, and PCP/PCC ratios ranged from 0.4 to 630. PCC at these levels did not appear to contribute significantly to the Incidence of adverse clinical reactions. © 1979 Oxford University Press.
