Chlorobiphenylols. Thin-layer chromatography and colour reactions of some hydroxylated chlorobiphenyls

The thin-layer chromatographic (TLC) behaviour and the colour reactions of 20 chlorobiphenylols (i.e., chlorohydroxybiphenyls) and the corresponding monohydroxy- and dihydroxybiphenyls have been studied and a number of correlations between structure and chromatographic properties made. Particular attention has been paid to the use of TLC in combination with mass spectrometry for the detection and identification of these compounds using non-destructive complexing spray reagents and dansyl derivative formation.
