Notes:
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 Na2HPO4 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.
