Step 1: Understanding the Concept:
Aspirin is one of the most famous and widely used drugs in the world. It was synthesized by acetylating salicylic acid to reduce its gastric irritation while maintaining its analgesic properties.
Step 2: Detailed Explanation:
1. Synthesis: Salicylic acid (\(o\)-hydroxybenzoic acid) reacts with acetic anhydride in the presence of an acid catalyst.
2. Reaction: The hydroxyl group (\(-OH\)) of salicylic acid is converted into an acetyl group (\(-OCOCH_3\)).
3. Product: The resulting molecule is Acetylsalicylic acid. It acts as a prodrug for salicylic acid but also has unique antiplatelet properties due to the irreversible acetylation of the COX enzyme.
Step 3: Final Answer:
The official chemical name of Aspirin is acetylsalicylic acid.
