Aspirin is a pain reliever and fever reducer, but if it's allowed to react with water then it can undergo hydrolysis, forming salicylic acid and acetic acid, which is no longer effective. Aspirin is only slightly soluble in water, so if we add it to the reaction mixture, the product would rather clump together than be in the water phase. Aspirin is also a carboxylic acid (CO 2 H) and an ester (CO 2 CH 3). The name "Ibuprofen" comes from its old chemical structure name: iso-butyl-propanoic-phenolic acid. Does aspirin contain an ester group, an acetoxy group, both, or another group which combines these two into one? Look for the carbonyl A drug would not be effective if the human body does not break down and absorb the drug easily. Salicylic acid is more polar than aspirin. It is also referred to as a R-OCO-R' group. These ionic salts of aspirin are sometimes marketed as "soluble aspirin". It takes about 48 hours to excrete an aspirin completely. So there's an ether Ester consists of a carbonyl group (CO) bound to an oxygen group. Several centuries later, in the 1800s, an active ingredient in this tea called salicin was discovered. The IR spectrum of hexane (C 6 H 14) is shown in the next figure. So this would be, we can go ahead and use a different color here. aromatic ring, our arene, and then we have an aldehyde. Solution. 2005 President, Sociedad Argentina de Cardiologa. This causes the solid to begin to form or precipitate. Learn about the hydrolysis of aspirin, whether aspirin is an acid or a base, and whether it is soluble in water. 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. side of the oxygen, isn't that an ether? Aspirin (acetylsalicylic acid) is an aromatic compound containing both a carboxylic acid functional group and an ester functional group. I am a chronic disease epidemiologist with a particular interest in the roles that individual lifestyle choices (diet, exercise, smoking), metabolic factors (obesity, high cholesterol, and hypertension), and biochemical and genetic markers play on the risk of cardiovascular disease and other chronic illnesses.
