The functional groups present in acetaminophen are hydroxyl, abbreviated OH, amide, abbreviated HN-CO-R and the aromatic group, which is known as the benzene ring. It is an aromatic compound and a weak acid (Paracetamol).
Acetaminophen is also known as Paracetamol, and it is used as a pain reliever and fever reducer. In acidic conditions, acetaminophen is subject to hydrolysis which causes it to produce an amine and a carboxylic acid. Acetaminophen can also be made using phenol if it goes through nitration, reduction and formation of the amide. There are several brands of acetaminophen, and the difference between them can be determined when their solubility in water at different temperatures is examined (Paracetamol).
