Synthesis of Acetylsalicylic Acid Essay Example for Free

A series of experiments based on aspirin have been used in our high school chemistry laboratory. Experiments include (i) synthesis, purification, and characterization of aspirin by mp and TLC, (ii) percentage composition of a commercial aspirin tablet by titration, (iii) kinetics of the hydrolysis of aspirin to salicylic acid under various conditions, (iv) synthesis and characterization of copper(II) aspirinate and copper(II) salicylate, and (v) reaction of copper(II) aspirinate in aqueous solution.

Both Celebrex and Vioxx made the 2001 list of top ten drugs by global sales, beating the famous impotence drug Viagra, introduced in 1998. Clinical superiority is not the only reason for the high dollar sales of COX2 inhibitors. Another reason is that super aspirins are much more expensive than aspirin. Social critics grumble that the new drugs are not worth their high prices, but people whose drug bills are covered by health insurance do not care. They demand the best, whether or not aspirin upsets their stomachs; they pay the same insurance premium anyway. COX2 inhibitors grossed $5.7 billions and accounted for 23 percent of the pain and inflammation drug market in 2001. That was smaller than the 30 percent for the old COX inhibitors, but the trend of replacement was unmistakable. Optimistic analysts projected that by 2010, the market share of COX2 inhibitors would more than double that of COX inhibitors.

Further Analysis THE END Presented by MY LIFE: YOU LIGHT IT UP Conclusion The overall objectives of this experiment were to synthesize aspirin, to perform a crude purity test on said aspirin, to standardize and prepare solutions of both NaOH and HCL, and to qualitatively determine the purity of the aspirin by finding the percentage of acetylsalicylic acid in the aspirin.

How to Make Aspirin - Acetylsalicylic Acid - ThoughtCo

Soon after chemical extracts and synthetics appeared, they were in demand. Supply of drugs came from two kinds of companies, pharmacies and chemical manufacturers. Some pharmacies, which traditionally prepared the portions prescribed by physicians, set up laboratories and factories and morphed into pharmaceutical firms. Among them was Merck, an early seller of salicin. As foundation of the modern science-based pharmaceutical industry, however, pharmacies were perhaps less important than manufacturers of fine chemicals – to this day the U.S. national accounting classifies pharmaceuticals under “chemicals and allied products.”

Synthesis and Characterization of Aspirin | Aspirin | …

To discover what a thing is good requires knowledge about relevant situations, which are often subtle and difficult. Lack of such knowledge partly explains why many chemicals sat on the shelf for decades before their therapeutic values were realized. This happened to aspirin’s rival Tylenol. Its active ingredient was synthesized in 1878, but had to wait until 1955 before being developed into a popular drug. Ever more revealing are the stories of antibacterial drugs. Sulfanilamide was synthesized in 1908, but it was the discovery of its therapeutic effectiveness in 1932 that won a Nobel Prize. Penicillin was discovered in 1928 and its therapeutic properties in 1939, and both discoveries were cited in the Nobel Prize. In Nobel Prizes such as these, the scientific community acknowledges the equal scientific importance of discovering and developing a drug. Unfortunately, this point is often overlooked in science studies, so that Hoffmann is often accorded with the credit for aspirin, to the neglect of Eichengrün and others in Bayer.

The history of aspirin (also known as acetylsalicylic acid or ASA) ..

Aspirin works. Willow bark works; it is available as herbal medicine and clinical trials find it effective against osteoarthritic pain. The old NSAIDs work. Chemical analysis brought more knowledge about are working – chemical molecules whose structures are known precisely. However, for seven decades physiological and pharmacological knowledge of the old NSAIDs did not advance much beyond that of willow bark. Both remained on the empirical and phenomenological level. People knew from experience aspirin worked, but lacked scientific knowledge about it worked and it worked like its cousins. aptly called it in 1966: “The wonder drug nobody understands.”
