Dutt, Manesh Chandra published the artcileUse of ninhydrin as a spray reagent for the detection of some basic drugs on thin-layer chromatograms, HPLC of Formula: 2508-72-7, the publication is Journal of Chromatography (1980), 195(1), 133-8, database is CAplus.
In a study aimed at exploring the potential of ninhydrin [485-47-2] to produce colored spots on thin-layer chromatog. plates, a wide variety of colors, on a white background, were produced by 52 of the 56 bases studied. In most instances different colors were produced at each of the selected temperatures (80, 120, and 160°), e.g., with amphetamine sulfate [60-13-9] the colors produced were pink-violet, grey-brown, and red-brown, resp. The response of the compounds to this method varied from 20 μg at room temperature to 1 μg at 160°.
