    EXPERIMENT 15 Thin-Layer Chromatographic Analysis of Drug Components Experiment Objective: To identify the components of an analgesic drug tablet and then correctly identify the tablet from a group of others with acquired data. Experiment Summary: In this experiment‚ we use TLC to identify components of an unknown analgesic drug. We prepare a solution of the drug by dissolving part of a tablet in 1:1 ethanol/dichloromethane‚ then spotting a TLC plate with the solution along

    of the Experiment: The intention of the experiment is to use solvent extraction methods to separate a mixture containing a carboxylic acid and a neutral compound. Once recovered‚ the solids were purified by recrystallization and examined by thin-layer chromatography‚ and their identities were derived by melting point and infrared (IR) spectroscopy. Extraction is a procedure that selectively dissolves one or more of the mixture compounds into a proper solvent. Extraction refers to the moving

    between the mobile and stationary phases. Subtle differences in a compound’s partition coefficient result in differential retention on the stationary phase and thus affect the separation. Thin layer chromatography (TLC) is a chromatographic technique that we use to separate the components of a mixture using a thin stationary phase such as silica plate supported by an inert backing. It applies mainly in medical‚ biological‚ chemical and pharmaceutical sciences because it is easy to be done and saves

    makes it a useful solvent for many chemical processes. The solid was already in powder form therefore we did not have to crush it but it the unknown was in a tablet form‚ one would need to reduce it to a powdery-like form in order to perform this Thin-Layer Chromatography experiment. The powder solution was thoroughly mixed with a glass rod in the test tube containing

    It was concluded that the product created was paracetamol when a thin layer chromatography test was performed and observed under ultraviolet light (which is discussed further down the page). An unknown substance was treated with acetic anhydrate and resulted with paracetamol. A compound that behaves in this matter is 4-aminophenol and is widespread in the industrial production of this drug. Upon these observations was the build up of “Chemical A” decided.   When 4-aminophenol is t treated with

    unknown amino acid. Within experimental error‚ the results were consistent with the reference literature cited in this report. Experimental Thin Layer Chromatography The amino acid standards used in this experiment were Alanine‚ Glycine‚ Serine‚ and Histidine. These standards and the unknown were separated by performing a method of chromatography. Thin layer chromatography (TLC) was performed by using a mobile phase and a stationary phase. The mobile phase was a nonpolar solvent composed of ethanol
