List of organic compounds

This page aims to list well-known organic compounds, including organometallic compounds, to stimulate the creation of Wikipedia articles. Note that purely inorganic compounds, minerals, and chemical elements are not included on this list. There are also no generic terms (e.g., carbohydrate) or mixtures of no fixed composition (e.g., naphtha, gasoline). Compounds and enzymes that are overwhelmingly of interest to biochemists, such as Cytochrome c peroxidase, are listed under list of biomolecules.

This list is not necessarily complete or up to date — if you see an article that should be here but isn't (or one that shouldn't be here but is), please update the page accordingly.

For substances with a number prefix such as 2-Butanol or 1,3-Cyclohexadiene, please use the first letter of the name (in this case under B or C) to find the compound. Note that such names usually have the first letter capitalized in a title or at the beginning of a sentence.
