AB - Abstract Thin-layer and paper chromatography of 14C-labeled cyanuric acid [2,4,6-tris(hydroxy)-s-triazine], ammelide [2-amino-4,6-bis(hydroxy)-s-triazine], ammeline [2,4-bis(amino)-6-hydroxy-s-triazine], N-ethylammelide [2-ethylamino-4,6-bis-(hydroxy)-s-triazine], N-ethylammeline [2-amino-4-ethylamino-6-hydroxy-s-triazine] and hydroxysimazine [2,4-bis(ethylamino)-6-hydroxy-s-triazine] are reported. Solvent systems contained a nonacidic organic solvent (butanol, benzene, or toluene) acetic acid, and water. Relationships between molecular structure of the triazine compounds and chromatographic mobility are evident. Replacement of one or two hydroxyl groups of cyanuric acid or one of N-ethylammelide with amino groups resulted in decreased thin-layer mobility. Substitution of one or both of the amino groups of ammeline or the amino group of ammelide with an ethyl group resulted in increased mobility. Similar trends were observed on paper chromatograms except that replacement of the second hydroxyl of cyanuric acid or an N-ethylammelide hydroxyl with an amino group resulted in a slight increase in mobility. Problems encountered with thin-layer and paper chromatography of the 14C-labeled hydroxy-s-triazines, including use of these methods for their purification, are discussed.
