**Step-by-Step Solution:**

1. **Understanding Aspirin**: Aspirin is a common medication used for pain relief, fever reduction, and anti-inflammatory purposes. Its chemical name is acetylsalicylic acid.

2. **Identifying the Structure**: The structure of aspirin consists of a benzene ring with an acetyl group (O-C-O-CH3) and a carboxylic acid group (COOH) attached to it. This makes it 2-acetoxybenzoic acid.

3. **Chemical Reaction**: Aspirin is synthesized from salicylic acid by reacting it with acetic anhydride (or acetyl chloride) in the presence of an acid catalyst (like sulfuric acid). During this reaction, the hydroxyl group (-OH) of salicylic acid is replaced by an acetyl group, forming aspirin.

4. **Conclusion**: Among the options provided (barbituric acid, seconal, chloroxylenol, and acetyl salicylic acid), the correct answer is acetyl salicylic acid, which is another name for aspirin.

5. **Properties of Aspirin**: Aspirin is classified as an analgesic (pain reliever) and antipyretic (fever reducer), making it effective for treating various conditions.

**Final Answer**: Aspirin is acetyl salicylic acid.
