“Thin-layer chromatographic differentiation of amphetamine from other primary-amine drugs in urine”.
Clin Chem. 1974 Feb 05;20(2):302-4.
We describe a thin-layer chromatographic procedure for distinguishing among amphetamine, mescaline, 4-methyl-2,5-dimethoxyamphetamine SIP, 3,4-
methylenedioxyamphetamine MDA, phenylpropanolamine, chlorphentermine, &946-phenylethylamine, benzocaine, and procaine. These compounds may be encountered in urine-screening programs, and all except MDA are well separated from amphetamine
a fact not previously established as well as from each other. They are revealed by sequentially spraying with ethanolic phenylacetaldehyde-ninhydrin and aqueous sodium phosphate. The resulting yellow spots fluoresce green on heating. The aromatic amines fluoresce poorly. MDA is distinguished from amphetamine by overspraying with chromotropic acid. Detection limits and R1 values are reported. Fluorescence spectra of the aliphatic amines are similar.
