A substance that is consumed in the course of a chemical reaction. It is sometimes known, especially in the older literature, as a
reagent, but this term is better used in a more specialized sense as a test substance that is added to a system in order to bring about a reaction or to see whether a reaction occurs (e.g. an analytical
reagent).
