Quick overview of where information is available about a chemical across public repositories

ChemAgora ( is a new chemical information portal launched by the European Commission's Joint Research Centre in October 2014.

Chemicals can be searched by their name, (also partial), CAS Registration number, InChIKey or chemical structure (by drawing the molecule in an appropriate editor). Once either of these search criteria is entered, the JRC service searches through a series of public repositories (currently twelve) and offers clickable links to the exact pages where more information about the chemical can be found.  The tool also provides a list of synonyms the chemical is known under.

Using ChemAgora, third party data bases can be searched by an identifier originally not available in these repositories: For example, the OECD'seChemPortal (one of the third party sites ChemAgora is using) becomes implicitly searchable by chemical structure when searched through ChemAgora. Thus ChemAgora does not only come in handy when getting an overview of what is currently known about a substance, it also adds value to third party systems.

ChemAgora has been developed by the JRC under the European Union's Seventh Research Framework Program (FP7) project diXa (Data Infrastructure for Chemical Safety), and is now available both via the diXa portal and as a standalone JRC application.
