Aspirin to Acetaminophen - Part 6 of 6: Acetaminophen from p-aminophenol

This is the final part of the series, where the p-aminophenol is converted to the acetaminophen. Using acetic anhydride, the p-aminophenol is going to be acetylated. The reaction is carried out in water at room temperature. Acetic anhydride does react with water, but it happens slowly.

Acetaminophen/Paracetamol (Tylenol)

Acetaminophen, more commonly known by brand names such as Tylenol, is not a true NSAID, as it does not have anti-inflammatory properties. However, it is commonly discussed alongside NSAIDs as it has similar antipyretic and analgesic properties. Although its mechanism of action is not well-
