TLC of 14 racemic alcohols (1-acenaphthol, a-tetralol, 1-indanol, Troger's base, trans-2-phenyl-1-cyclohexanol, 1-phenyl-ethanol, 1-phenyl-propanol, 1-phenyl-1,2-ethanediol, 1-phenyl-1,3-propanediol, 2-phenyl-2-butanol, 2-phenyl-1,2-propanediol, 2-phenyl-3-butyn-2-ol, 1-phenyl-2-propanol, 1-phenyl-2-butanol) on plates prepared from mixtures of CTB (cellulose tribenzoate) and silica gel. Mixtures of ethanol - water and of n-hexane - 2-propanol were investigated as mobile phases. Visualization by exposure to iodine vapor for 24 h. Troger's base was detected under UV 254 nm. Densitometric measurements of a-tetralol and 1-indanol were performed.

A study of the mechanism and thermodynamics of retention. J. Liq. Chromatogr. Relat. Technol. 28, 2499-2513 (2005). TLC of R,S-(+/-)-ibuprofen and S-(+)-ibuprofen on silica gel prewashed with methanol - water 9:1 and impregnated with a 0.03 mol/L methanolic solution of L-arginine by dipping. Separation with acetonitrile - methanol - water 5:1:1 and several drops of acetic acid to adjust the pH to 4.8. Two dimensional development with the same mobile phase in the first direction, followed by drying and application of the S-(+)-enantiomer and development in the second direction. Densitometric evaluation at 210 nm. Chiral separation of propanolol with acetonitrile - methanol 15:4 containing ammonia for one and two dimensional separation.

J. Planar Chromatogr. 21, 43-47 (2008). TLC and polarimetry was used to investigate the tendency of L-alanine to undergo oscillatory in-vitro chiral inversion when dissolved in neutral, acidic, and basic solvents. The influences of temperature and sample mixing were investigated as well. It was confirmed that L-alanine undergoes chiral inversion. TLC of L-alanine on silica gel, prewashed with methanol - water 9:1, and impregnated twice with aqueous copper sulfate solution and L-proline in water - methanol 9:1. Development with 2-propanol - acetonitrile - water 6:2:3 at 22 °C. Detection by dipping in freshly prepared 0.2 % methanolic ninhydrin solution, followed by heating at 100-110 °C for 10 min. Quantitation by densitometry at 540 nm.

Analytical Chemistry, An Indian Journal 9(3) (2010). HPTLC of a racemic mixture of oxybutynin chloride on chiral phase with toluene – acetone – methanol 8:1:1. Both enantiomers were well separated with hRf values of 47 and 63. The identity of the isomers was established by on-line UV, NMR and MS data. The method was validated using NP-TLC and the same mobile phase. The method was linear in the range of 50-350 µg/band with a recovery of 98.2-101.7 %.

J. Chromatogr. Sci. 56 (1), 92-98 (2018). TLC for direct enantiomeric resolution of the racemic β-adrenolytics bisoprolol (1), atenolol (2), propranolol (3), salbutamol (4) and carvedilol (5) by TLC using bovine serum albumin (BSA) as chiral additive in the stationary phase and with different compositions of simple organic solvents without buffer or inorganic ions. Systematic investigation of the effect of variation in pH, temperature, amount of BSA as the additive, and composition of mobile phase on resolution. Detection by exposure to iodine vapors. The five entantiomers were separated in the elution order (1), (2), (3), (4), and (5). The LOD was 0.7, 1.2, 0.8, 1.6 and 0.9 μg/zone for (1), (2), (3), (4), and (5), respectively.
