It’s helpful use is to give aid to those who are suffering from toothaches‚ common colds‚ chest pain‚ headaches‚ and many more symptoms of mild pain‚ fever‚ or inflammation. It is also known to reduce blood clotting. Its scientific name is acetylsalicylic acid (ASA)‚ with it’s chemical formula being C9H8O4‚ and its IUPAC name being 2-acetyloxy

FOUNDATION IN SCIENCE INTRODUCTION TO PRACTICAL ORGANIC CHEMISTRY – MAKING AND PURIFYING ORGANIC COMPOUNDS Stage 1 – Deciding how much reagent to use Most organic reactions do not go to completion; most reach an equilibrium position with significant quantities of reactants still remaining. In addition‚ separating the desired product from the rest of the reaction mixture‚ and then purifying it‚ will result in the loss of more of the product. The amount of product obtained expressed as a percentage

What is Aspirin? Aspirin is on of the first drugs to ever be commonly used and is still one of the most widely used in the world. How widely used you ask? Approximately 35000 metric tonnes are produced and consumed every year. Chemically aspirin is known as acetylsalicylic acid with the chemical formula of C9H8O4. Aspirin is an analgesic‚ anti-inflammatory‚ antipyretic‚ and is an inhibitor of platelet aggregation. The history of Aspirin Aspirin has been a major part of just about everyone’s

“Aspirin has been used for many years; it is well-understood‚ effective‚ inexpensive and widely available.” - Dr. Jeffrey Berger In the last 30 years medicines prescribed by doctors have changed beyond all recognition. Our better knowledge of the nature of diseases and their management has led to the replacement of many old remedies by new ones specifically designed for each illness. Everyone has known for years that

IB1 Chemistry Practical #8 ANALYSIS OF ASPIRIN TABLETS For a long time the bark of the willow tree (salix alba) was used as a traditional medicine to relieve the fever symptoms of malaria. In the 1860’s chemists showed that the active ingredient in willow bark is salicylic acid (2-hydroxybenzoic acid) and by 1870 salicylic acid was in wide use as a pain killer (analgesic) and fever depressant (antipyretic). However‚ because it is a relatively strong acid‚ salicylic acid has the undesirable side effect

Aspirin Aspirin is a salicylate‚ also known as a non steroidal anti-inflammatory drug (NSAID). It is the generic name of acetylsalicylic acid and is used clinically to treat fever‚ pain and inflammation as it works by preventing the formation of prostaglandin. Prostaglandin is the active agent that is responsible for the sensitisation at the nerve endings. It can be administered orally‚ rectally or by intravenous route.

Synthesis of Aspirin and Tylenol Kyla Wykoff Abstract Aspirin and Tylenol were synthesized by means of crystallization‚ recrystallization‚ and melting point determination. Synthesis produced significantly high percent yields for aspirin‚ however‚ produced extremely low and impure percent yields for Tylenol. A second group was also used to compare results and errors‚ in which they too were also producing extremely low percent yields of Tylenol. Therefore‚ error was based on the specific protocol

Liquid Chromatography Analysis of Aspirin Problem: Was aspirin (acetylsalicylic acid) successfully synthesized? Are there impurities or by-products present in the synthesized aspirin? How pure is the synthesized aspirin? Introduction: In the last experiment‚ aspirin was synthesized followed by characterization of the product using several different techniques. Melting point was a test that provided information about the identity and purity of the aspirin product. The iron(III)chloride test

Today‚ aspirin is one of the most widely used medication on this Earth and has been since its popular breakout in the late 1890s. Long before we were born there was no such thing of a medication called aspirin. Instead‚ ancient people used willow leaves and bark from trees to help relieve oneself from pain and fevers. Aspirin as we come to know it in the form of an acetylsalicylic acid‚ was introduced to the world by Chemist Felix Hoffmann who was working at Bayer pharmaceutical company located in
