This is a list of common chemical compounds with chemical formulas and CAS numbers, indexed by formula. This complements alternative listing at inorganic compounds by element. There is no complete list of chemical compounds, since by nature the list would be infinite.

Note: There are elements for which spellings may differ, such as aluminum/aluminium, sulfur/sulphur, and cesium/caesium.
