How to Use eChemPortal

Under Chemical Substance Search you can search for information by chemical number (recommended) or by chemical name and synonym, including partial names, in several languages.

You can then search for specific endpoint property data for the substances you selected under Search. You can also go directly to Chemical Property Data Search without specifying chemical substances.

Under Chemical Property Data Search you can query the eChemPortal data catalogue by chemical property and can select specific search criteria for this property. You can save search results on chemical properties for different chemicals to your local computer.

See the “Help” text and the list of Frequently Asked Questions to learn more about how to use the Portal.
