Dutt, Manesh Chandra published the artcileIdentification of basic drugs by the thin-layer chromatographic profiles of their ninhydrin complexes, Synthetic Route of 2508-72-7, the publication is Journal of Chromatography (1981), 206(2), 267-77, database is CAplus.
Fifty-two common basic drugs produce various colors when spotted with ninhydrin [485-47-2] on plastic thin-layer plates and heated. When the plate is then developed in a suitable solvent each of the colored spots separates into a variety of addnl. colored spots and patches, the number of which depends on the temperature of heating. The relative intensity and spatial arrangement form a profile that is highly characteristic of the compounds The formation of such profiles was investigated at 100 and 160°C.
