Key Concepts

Chemical Formula

A chemical formula represents the composition of a compound, indicating the types and numbers of atoms present. In the case of Demerol, C₁₅H₂₂ClNO₂, the formula shows that the compound contains 15 carbon (C) atoms, 22 hydrogen (H) atoms, 1 chlorine (Cl) atom, 1 nitrogen (N) atom, and 2 oxygen (O) atoms, which are essential for understanding its structure and properties.

IUPAC Nomenclature

The International Union of Pure and Applied Chemistry (IUPAC) nomenclature provides a systematic way to name chemical compounds based on their structure. Understanding IUPAC rules is crucial for identifying the correct names of compounds like Demerol, as it helps in recognizing the functional groups and the overall structure of the molecule.

Pharmacological Classification

Pharmacological classification categorizes drugs based on their effects, mechanisms of action, and therapeutic uses. Demerol, known generically as meperidine, is classified as an opioid analgesic, which is important for understanding its role in medicine, including its pain-relieving properties and potential side effects.
