2a: Infrared Spectroscopy and Analgesic Drug Identification Abstract: To be able to understand how organic soluble compounds could be isolated from non-organic components‚ a chromatographic separation process was used. The objective of the analgesic drug identification is to isolate the organic compounds/ active ingredients in an unknown drug. The identity of the drug was determined through melting point‚ percent recover‚ and Rf values. The comparable data for acetaminophen from the manufacturer

Preparation of an Ester Acetylsalicylic Acid (Aspirin) OBJECTIVE: To become familiar with the techniques and principle of esterification. DISCUSSION: Aspirin is a drug widely used as an antipyretic agent (to reduce fever)‚ as an analgesic agent (to reduce pain)‚ and/or as an anti-inflammatory agent (to reduce redness‚ heat or swelling in tissues). Chemically‚ aspirin is an ester. Esters are the products of reaction of acids with alcohols‚ as shown in the following equation using

Factors that may cause migraine HORMONAL CHANGES Hormonal changes are known as a trigger. In some people‚ mograines occur without an actual reason‚ and for others they only experience migraines when they are exposed to a trigger. A trigger for one person will sometimes not be the same for another. In this case females who experience migraines‚ may experience hormonal changes as a trigger and only get attacks during their period‚ although there are others who have multiple triggers and this could

Experiment 3: The preparation of acetaminophen (paracetamol) with thin layer chromatography (TLC) to monitor the reaction. Abstract: This experiment is to demonstrate the preparation of paracetamol and its properties. Reflux and filtration of 4-aminophenol and acetic anhydride formed the crude sample. Further analysis of dry white crystals were used to give quantitative measurements and a percentage yield of 46% was obtained. The overall conclusion is that the acetic anhydride reacted with the

Abstract Acetic Anhydride and p-Aminophenol were heated in a vial attached to an air condenser to synthesize crude acetaminophen‚ resulting in 0.097 grams (47.48% yield). The crude acetaminophen was then recrystallized in a solvent of water and methanol over heat resulting in 0.082 grams (39.61% yield) of pure acetaminophen. Melting points of both crude and pure acetaminophen were taken‚ and found to be 165.9 - 170.9°C and 168.2 - 171.5°C‚ respectively. The literature melting point of acetaminophen
