Identify the functional groups in both. Let’s go back and look at the chemical name of aspirin, acetylsalicylic acid. Salicylic acid is treated with acetic anhydride, an acid derivative, causing a chemical reaction that turns salicylic acid's hydroxyl group into an ester group (R-OH → R-OCOCH3). Ester consists of a carbonyl group (CO) bound to an oxygen group. Its IUPAC name is 1,3,7-trimethyl-1H-purine-2,6(3H,7H)-dione 3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione. There are three functional groups found in aspirin: It is also referred to as a R-OCO-R’ group. Aspirin is the most widely used over-the-counter drug in the world.
