Aspirin, therefore, has an analgesic (reduces pain), anti-inflammatory (reduces redness and swelling), anti-platelet (reduces blood clots) and antipyretic (temperature reduction) effects1,2,3. In order to complete the second product, acetic acid, the hydrogen can be removed with a weak base: Under basic conditions we have a hydroxy group, which attacks the carbonyl. What functional groups are found in aspirin? Posted 7 years ago. We have a carbonyl and These functional groups include carboxylic acid, ester, and an aromatic group. But at a higher temperature, such as 70 degrees Celsius, it would take less than 10 hours for all of the aspirin to be degraded. It is a non-selective NSAID as it irreversibly inhibits both cyclooxygenase (COX) enzymes involved in converting arachidonic acid to prostaglandins and thromboxane 3. Acetylsalicylic acid is a synthetic organic derived from salicylic acid. ring, so we know that an arene is present in atenolol, so let me go ahead and write this in here. Inside the body, aspirin is converted into its active metabolite salicylate. Aspirin is prepared by chemical synthesis from salicylic acid, through acetylation with acetic anhydride. Esterification & Reflux Purpose & Reaction | What is Reflux? You can also see a benzene ring on the left side. In esters, the carbonyl carbon is bonded to an oxygen which is itself bonded to another carbon. 2. with this compound. Thanks in advance! So now we are talking about an alcohol, so this is an alcohol. Because hexane has only C-H and C-C bonds (and no functional groups), this spectrum can help orient you to the important regions in an IR spectrum. Let me change colors, let me do blue. Since we are in a basic environment we don't have any extra hydrogens, so we can't hydrogenate both products.
