Proc. Intern. Symp. on Planar Separations Plan. Chrom. 357-362 (2003). Investigation of the retention behavior of thiazoles as function of organic modifier content of the eluents using two types of stationary phases. TLC of 12 3-benzyloxycarbonyl-5-substituted 2,4-dioxotetrahydro-1,3-thiazoles on silica gel, impregnated with paraffin oil, and rice starch with NH3 conc. - methanol, conc. NH3 conc. - dioxane, and NH3 conc. - acetone with different modifier content (from 0.01 to 0.34 ) for methanol, dioxane, and acetone. Visualization under UV 254 nm.

J. Liq. Chromatogr. Relat. Technol. 31, 3020-3031 (2008). TLC of twelf thioazines on silica gel with chloroform - ethanol 10:1 and chloroform, and on aluminum oxide with dichloromethane and benzene - chloroform 1:1 in a chamber saturated for 30 min. Detection under UV 254 and 366 nm. The retention parameters were measured and then calculated as separation factors deltaRf, RS, and alpha. The hRf values were correlated with the dipole moments of thioazines and the symmetry of diazinodithiins.

J. Chromatogr. 441, 454-457 (1988). TLC of 12 sulfa drugs on six different layers with four solvent systems using acetoacetanilide as coupling agent.

J. Planar Chromatogr. 7, 484-486 (1994). TLC of ß- and g-quinolinyl sulfides (1,4-dithiinoldiquinolines, o,o'-dimethylthiodiquinolinyl sulfides, unsubstituted ß,g-diquinolinyl sulfides, methylthioquinolines) on silica with chloroform - methanol 98:2 and on aluminium oxide with carbon tetrachloride - chloroform 85:15. For determination of values of lipophilicity index, RMO, the TLC plates were impregnated by overnight predevelopment with hexane - paraffin oil 95:5. Aqueous methanol (concentration between 60 and 80%) was used as eluent. Inspection under UV 360 nm.

J. Planar Chromatogr. 17, 323-327 (2004). TLC of three 1,2-dithioles and five 2-alkylidene-4-oxothiazolidines on RP-18 with binary mixtures of methanol and water, tetrahydrofuran and water, and acetone and water in different proportions. Detection with iodine vapor. Good correlation of chromatographically obtained lipophilicity data with calculated log P values.

J. Liq. Chromatogr. Relat. Technol. 33, 957-971 (2010). HPTLC of pyritinol on silica gel with dichloromethane - methanol - formic acid 9:1:1 in a twin trough chamber. Quantitative determination by absorbance measurement at 300 nm. Repeatability and intermediate precision in matrix were 0.4 % and 3.0 %, respectively. Recoveries of spiked samples at three levels ranged from 98.5 to 101.9 % with intermediate precisions of RSD 3.7 to 4.7 %. The limit of detection and quantification was 0.6 and 2.0 µg/mL (6 and 20 ng/band), respectively. Selectivity was evaluated determining the peak purity by UV-spectrophotometry and showed correlation coefficients (r) > 0.9997. Additionally the selectivity was proven by mass spectrometry. Mass spectra showed only the analyte signals which indicated a highly satisfying selectivity.

TLC of isothiazolone formulations, used for preservation of cosmetics and technical products, on silica with 6 different solvent systems. Detection with 10 spray or detection methods (e.g. Dragendorff reagent, iodine vapours, UV 254 nm).
