Chemistry has a number of specific databases, ranging from bibliographic information to the research of the structure or properties of compounds. We set out here a selection of these tools.

Commercial tools

The main tools of chemical research are accessible at EPFL (computer connected to the network of the school or VPN):

  • Scifinder: interface for the Chemical Abstracts and associated Chemical Abstracts Service databases. Before connecting for the first time, it is essential that you register on our registration page with an EPFL email address. The Terms of Use imposed by CAS are quite strict (User Agreement): access only by EPFL staff or students, only in the context of training or research work of a non-commercial nature etc.
  • Reaxys: Web interface for the Beilstein databases (organic chemistry), Gmelin (inorganic chemistry) and the Patent Chemistry Database of MDL.
  • Cambridge Structural Database: database of crystal structures containing carbon, the licence for which is managed by the Ecole Polytechnique Fédérale in Zurich for Swiss universities. Contact Michael Wörle to obtain access.

Free tools

There are also chemical search tools freely accessible online:

  • Chemspider: database of the Royal Society of Chemistry, integrating structures and other information on more than 30 million compounds from several hundreds of sources. The users can take part in the project and enhance the database or correct data.
  • PubChem: information about the molecules of biological interest up to 1000 atoms, managed by the American National Library of Medicine.
