What is the synthesis of aspirin?
Aspirin is prepared by chemical synthesis from salicylic acid, through acetylation with acetic anhydride. The molecular weight of aspirin is 180.16g/mol. It is odourless, colourless to white crystals or crystalline powder.
What is another name for aspirin?
Aspirin is a generic drug sometimes referred to as acetylsalicylic acid (ASA). It is an NSAID that treats inflammation and prevents the formation of blood clots.
What is the importance of aspirin?
It does a good job of relieving pain and bringing down fevers. It has also been shown to reduce the risk of heart attack, stroke, and colon cancer. It can even stop heart attacks and strokes in their tracks. In fact, if you’re in your 50s or 60s, you may want to think about taking a low-dose aspirin every day.
How would you describe aspirin?
Aspirin is known as a salicylate and a nonsteroidal anti-inflammatory drug (NSAID). It works by blocking a certain natural substance in your body to reduce pain and swelling.
What is the electrophile in aspirin synthesis?
Because acetyl salicylic acid, aka Aspirin, has an acetate group, and acetic anhydride has one that is a good leaving group.
What is the mechanism of action of aspirin?
Aspirin is non-selective and irreversibly inhibits both forms (but is weakly more selective for COX-1). It does so by acetylating the hydroxyl of a serine residue. Normally COX produces prostaglandins, most of which are pro-inflammatory, and thromboxanes, which promote clotting.
What is mechanism of action of aspirin?
Who invented the aspirin?
Felix HoffmannAspirin / Inventor
In 1897, Felix Hoffman, a German chemist working for the Bayer company, was able to modify salicylic acid to create acetylsalicylic acid, which was named aspirin (Fig. 1).
How did aspirin change history?
By providing an easy and inexpensive method to alleviate pain, aspirin began to change the experience and expectations of patients and doctors and ultimately the nature of modern medicine itself.
Is aspirin a technology?
Electronic Aspirin Market | A Detailed Review and Outlook Study Report to 2025. Electronics aspirin refers to a medical technology driven by and for patients to relieve pain, e.g., cluster headaches, migraines, and other types of head and facial pain.
What is the purpose of the synthesis of aspirin lab?
The purpose of this lab was to synthesize Aspirin and measure the synthesized Aspirin’s purity. By calculating the theoretical yield based on the original amount of Salicylic acid, one could determine the actual yield percentage of the reaction.
Which reaction mechanism explain the synthesis of aspirin?
Principle: Synthesis of aspirin from salicylic acid occurs by acetylation process in acidic medium. Salicylic acid interacts with acetic anhydride in presence of few drops of concentrated sulphuric acid to produce aspirin and a molecule of acetic acid.

What is the purpose of LAB 6 of aspirin synthesis?
Lab 6: Synthesis of Aspirin Conclusion In Part 1, the purpose of the lab is to prepare acetylsalicylic acid, commonly called aspirin, and determine the experiment yield of a synthesis of Aspirin. Aspirin is synthesized in a laboratory.
What is the chemical name for aspirin?
Aspirin, the ubiquitous pain reliever, goes by the chemical name acetylsalicylic acid. One of the compounds used in the synthesis of aspirin is salicylic acid, which is itself a pain reliever that was known to many ancient cultures, including the Native Americans who extracted it from willow tree bark.
What are the sources of error in the synthesis of aspirin?
Sources of error that were possibly present in the synthesis of aspirin lab are an improperly calibrated balance, an inaccurate hot plate, contamination of the substances, age of the substances, or contamination of the glassware.
