Which term denotes the scientific name of a drug's chemical structure?

• A. Generic name
• B. Trade name
• C. Chemical name
• D. Official name

Answer: (C)

Understanding naming in pharmacology, the term that conveys the exact scientific description of a drug’s chemical structure is the chemical name. It’s the systematic descriptor, often following IUPAC rules, that encodes how the atoms are arranged in the molecule. For example, the chemical name for aspirin describes its specific chemical composition and structure, even though clinicians commonly use the simpler, nonproprietary generic name “aspirin” or the brand trade name “Bayer Aspirin” in practice. The chemical name is used in chemistry and research contexts where precise structure matters, while the generic name and trade name serve everyday clinical communication.
