Why Reaxys

Reaxys is a database where you can find data about materials and reactions. This information is extracted from scientific journals in a smart way. This means that:

  • You can combine keywords with chemical structures or reactions in your search
  • You can cite directly from scientific literature

Reaxys extracts data from scientific literature and presents this in tables. This means you do not have to go through all the full texts to be able to find the correct data. It saves you a lot of time!

Who uses Reaxys?

Since this software is designed to search with chemical structures and reactions, this database is especially of interest for organic chemists.


Reaxys ( is a web-based, chemical search engine that allows to search for chemical reactions, (parts of) chemical structures and substance properties (e.g. spectra). In this libguide you can find more information about the possibilities of Reaxys with extra explanations and tutorials. Navigate through the different tabs in the top of the screen.
