What does the chemical name of a drug describe?

1. The drug's intended use

2. The drug's brand name

3. The drug's chemical composition

4. The drug's side effects

The correct answer is: The drug's chemical composition

The chemical name of a drug provides a precise description of its molecular structure and composition, detailing the specific arrangement of atoms and the chemical bonds that hold them together. It is a systematic name derived from the chemical structure of the compound, following the conventions set by the International Union of Pure and Applied Chemistry (IUPAC). This name is crucial for identifying the drug at a molecular level and is used by scientists and healthcare professionals for clarity in research and pharmaceutical development. While the intended use of a drug, its brand name, and potential side effects are important aspects of pharmacology and medicine, they do not pertain to the chemical name. The chemical name focuses solely on the scientific and structural characteristics of the drug itself.
