eChemPortal offers free public access to information on properties of chemicals:

eChemPortal allows for simultaneous search of multiple databases and provides clearly described sources and quality of data. eChemPortal gives access to data submitted to government chemical review programmes at national, regional, and international levels.

Users can search multiple sources of information simultaneously using a chemical substance name or CAS Registry Number and obtain direct links to the retrieved data within each site. For an efficient use of the search engine, tips and tricks are provided under General Information on the Portal. Users may also wish to consult the individual participant databases if they need to be assured that they have the most up-to-date information.

To ensure the portal meets your needs, we ask that you take a few minutes to complete a web survey to provide your opinions on how best to improve the site.
