Chemical inventories are used to provide access within IUCLID to inventories of information on chemical identity. A Reference substance may be linked to an entry in a Chemical inventory, to provide information on chemical identity in a standard format. Chemical inventories cannot be created from within IUCLID, but they can be imported, after which they are read-only.
