As well as an Introduction all class names included are listed alphabetically in the following files: A; B; C; D,E; F,G; H; I; K,L; M; N; O; P; Q,R; S; T; U-Z. Each class name then leads to a file of definitions of class names of related substances. These in turn may lead to other files from cross-references. Related classes are grouped together under the following headings.

1. Carbon, Hydrogen and Oxygen:
   • Acyclic Hydrocarbons
   • Ring systems
   • Alcohols, Ethers, Phenols and Derivatives
   • Aldehydes, Ketones, Quinones and Derivatives (See also oximes, azines, etc. under Nitrogen)
   • Carboxylic acids and derivatives (See also amides, amidines, etc. under Nitrogen)
2. Based on Other Elements:
   • Boron
   • Halogens
   • Metals
   • Nitrogen (one N atom only)
   • Nitrogen (two or more N atoms)
   • Phosphorus, Arsenic, Antimony and Bismuth
   • Silicon, Germanium, Tin and Lead
   • Sulfur, Selenium and Tellurium
3. Natural Products:
   • Antibiotics (-lactams and tetracyclins)
   • Carbohydrates (and cyclitols)
   • Lipids
   • Nucleic acids and component units
   • Terpenoids including retinoids and steroids
   • Tetrapyrroles and related compounds
   • Others natural products
4. Others:
   • Ions and Radicals
   • Miscellaneous.
