TLC of 4-methylbenzyl alcohol, 2-phenylethanol, 1-phenyl-1-ethanol, myristyl alcohol, isoborneol, menthol, cetyl and stearyl alcohol on silica with hexane - acetone 8:2. Detection with thymol blue and bromothymol blue (each dissolved in aqueous sodium hydroxide solution, 2 %, 100 mL), evaluation 10 min. after spraying, then heating at 110 °C for 10 min. and re-examination.

Journal of Pharmacy Research 4(5), 1401-1404 (2011). HPTLC of fluconazole and its structurally related impurities, on silica gel (prewashed with methanol) with n-butanol - water - acetic acid 8:2:1 with chamber saturation for 20 min. The hRf value of fluconazole was 67 and of the two separated impurities 49 (impurity B) and 79 (impurity E). Quantitative determination by densitometry in absorbance mode at 254 nm. The method was linear in the range of 1-6 µg/band for fluconazole and 0.5-2.5 µg/band for both impurities.

J. Planar Chromatogr. 8, 420-426 (1995). Introduction of a thermodynamic definition of a mixed (adsorption - partition) mechanism of solute retention in liquid chromatography on chemically bonded alkyl stationary phases, together with a practical example of how to quantify the complementary contributions, which certainly differ from one solute to another. - TLC of 5 higher fatty alcohols (lauryl, myristyl, cetyl, stearyl, and arachidyl alcohol) on silica with mixtures of 2-propanol - hexane, heptane, or octane, and t-butanol - hexane in different proportions. Detection by spraying with a 0.1% solution of Rhodamine B in water.

J. Planar Chromatogr. 24, 160-165 (2011). HPTLC of venlafaxine hydrochloride in bulk and formulations on silica gel with butanol - acetic acid - water 3:1:1. Quantitative determination by densitometry in absorbance mode at 284 nm. The hRf value was 58. Linearity was between 100 and 600 ng/zone. The limit of detection and quantification was 39 and 131 ng/zone, respectively. The repeatability and the intermediate precision (%RSD, n = 6), were between 0.3-0.7 % and 0.6-0.9 %, respectively. The recovery was between 99.1 and 101.7 %.

J. Chromatogr. 341, 426-431 (1985). TLC of the fluorescent derivatives formed from primary or secondary alcohols and 3-chloroformyl-7- methoxycoumarin on silica with benzene - ethyl acetate 8:2. Rf values and detection limits for several alcohols were given. 1) HPLC method was also described, 2) 17-oxosteroids were determined in urine from normal humans after enzymic hydrolysis, extraction, and derivatization with 3-chloroformyl-7-methoxycoumarin.
