title: Mass-spectrographic evidence of the conversion of p-chloroamphetamine to 3,4-dimethoxyamphetamine.
abstract: Intraventricularly injected p-chloroamphetamine (p-CA) was actively metabolized to 3,4-dimethoxyamphetamine (3,4-DMA) in the rat brain. Time-course experiments with intraperitoneally injected p-CA confirmed that the presence of cerebral 3,4-DMA was not due to its "one-pass" entry from the peripheral organs. The identity of 3,4-DMA from brain tissue and urine was established by comparison to authentic 3,4-DMA. The synthetic and biological samples were isographic in all analytical systems. 3,4-DMA from biological samples was verified by mass spectrography.
