Abstract
A thin‐layer chromatographic method is described for sulfonamides and some other chemotherapeutic compounds. Ion‐exchange resin precoated plates (Fixion 50 × 8 Na^+^, Chinoin, Budapest or Polygram Ionex‐25 SA‐Na, Macherey‐Nagel and Co.,Düren, FRG) are employed with Na~2~HPO~4~ or Na‐acetate (adjusted to different pH values) containing NaCl and tert‐butyl alcohol or ethanol as developing solvent system. For qualitative and/or semiquantitave determinations the chromatograms can be stained: (A) with o‐tolidine, after chlorination; (B) with p‐dimethylaminobenzaldehyde; (C) with p‐dimethylaminocinnamaldehyde.
