Thin-layer chromatography (TLC) is a chromatography technique that separates components in non-volatile mixtures. [1] It is performed on a TLC plate made up of a non-reactive solid coated with a thin layer of adsorbent material. [2] This is called the stationary phase. [2]
Phosphomolybdic is used as a stain for developing thin-layer chromatography plates, [4] staining phenolics, hydrocarbon waxes, alkaloids, and steroids. Conjugated unsaturated compounds reduce PMA to molybdenum blue. The color intensifies with increasing number of double bonds in the molecule being stained. [5]
Hazard statements. H301, H315, H319, H335: Precautionary statements. ... Semicarbazide is used as a detection reagent in thin layer chromatography (TLC).
Hazard statements. H315, H319, H335: ... In chemistry, bromocresol green is used in Thin-layer chromatography staining solutions to visualize acidic compounds.
A solution of para-anisaldehyde in acid and ethanol is a useful stain in thin layer chromatography. [4] Different chemical compounds on the plate can give different colors, allowing easy distinction. DNA breakage
KMnO 4 solution is a common thin layer chromatography (TLC) stain for the detection of oxidizable functional groups, such as alcohols, aldehydes, alkenes, and ketones. Such compounds result in a white to orange spot on TLC plates.
High-performance thin-layer chromatography (HPTLC) serves as an extension of thin-layer chromatography (TLC), offering robustness, simplicity, speed, and efficiency in the quantitative analysis of compounds. [1] This TLC-based analytical technique enhances compound resolution for quantitative analysis.
Mercaptoacetic acid in hair waving and depilatory products containing other mercapto acids can be identified by using thin-layer chromatography and gas chromatography. [24] [25] MAA also has been identified by using potentiometric titration with silver nitrate solution. [26]
