Use of Photocatalytic Reactions to Visualize Drugs in TLC

The numerous ways of visualization of organic substances separated by thin-layer chromatography (TLC) have been described in detail in the literature [1–7]. Despite of the recognition and use of various visualizing agents there is still a need for further research and testing of simple and useful methods for detection of organic compounds. Although the visualization of drugs separated on thin layers has been the subject of numerous studies [1, 8–12], use of photochemical processes in the presence of a catalyst for detection of drugs on TLC plates has not yet been used.
