Analgesics Analgesics‚ or painkillers‚ come in many varieties. Most consumers know the various brand names‚ but may not know that they are in different pharmacological classifications. For instance‚ Tylenol and Motrin are two drugs that behave differently on the human body to achieve similar results. While most consumers do not think about what they put into their bodies‚ maybe they should. They would find that the various painkillers could markedly affect the body differently. The most popular

Chromatographic Analysis of a Commercial Analgesic’s Active Component I. Abstract This study on Chromatographic Analysis of a Commercial Analgesic’s Active Component seeks to separate‚ identify‚ quantify and analyze the active component found in Biogesic®‚ which may be useful for public awareness despite its wide acceptance and availability in the market. Furthermore‚ this study applies thin layer chromatography (TLC) technique since it is the simplest‚ cheapest yet most effective approach in terms

In this TLC lab‚ we explored the relative polarities of Acetylsalicylic Acid‚ Ibuprofen‚ Acetaminophen‚ and Caffeine based on their functional groups. The most overall polar analgesic is considered to be the analgesic that contained the most polar function groups. The amine and amide functional groups are the most polar. In this experiment‚ we found that both these functional groups are found in Caffeine. As a result‚ Caffeine was the most polar out of Acetylsalicylic Acid‚ Ibuprofen‚ Acetaminophen

Chromatography of Commercial Analgesics Using the thin layer chromatography the major components of a commercial analgesic tablet will be indentified and purified. The active ingredients of the analgesic used were characterized by comparison with chromatograms of aspirin‚ acetaminophen‚ ibuprofen‚ mefanemic acid‚ and caffeine through the use of UV chromatography then the Rf value was calculated for each solvent. INTRODUCTION In this experiment‚ thin-layer chromatography (TLC) will be used to determine

not explored in this laboratory. This experiment explores these techniques to identify an unknown amino acid by TLC and analyze food colors using paper chromatography. By using 2.0 mL of dimethoxyethane and 18 mL of absolute ethanol as the developing solution‚ and then spotting each sample of amino acids and an unknown on the silica gel chromatography plate‚ we began the process of TLC plating. The ninhydrin solution was sprayed on the chromatography plate and allowed to dry. After allowing the solution

IDENTIFICATION OF UNKNOWN SOLUTIONS USING TLC CHROMATOGRAPHY Purpose: To become familiar with the principles and terminology of TLC chromatography to identify an unknown molecule based on comparisons with known laboratory standards and Rf factors. Background Thin Layer Chromatography: Chromatography is a sophisticated method of separating and identifying mixtures of two or more compounds. The separation is accomplished by the distribution of the mixture between two phases: one that

chromatography (TLC) is an extremely valuable analytical technique. It provides a rapid separation of compounds‚ and gives an indication of the number and nature of the components of a mixture. TLC can also be used to identify compounds by comparison with known samples‚ to check the purity of a compound‚ or to monitor the progress of a reaction‚ an extraction‚ or a purification procedure. This experiment will introduce you to the mechanics of TLC‚ and the chemical principles behind it. TLC is normally

It featured previously unreleased vocals from Left Eye.Billboard magazine ranked TLC as one of the greatest musical trios.[5] Between 1992 and 2002‚ the band had ten top ten singles‚ four number one singles‚ four multi-platinum albums‚ and won fiveGrammy Awards. At the end of 1999‚ TLC was ranked as the seventh most successful act of the 1990s by Billboard. In 2008‚ the group was inducted into the All Time Hot 100 Artist Hall of Fame
