New Web Interface for Beilstein/Gmelin

June 22, 2010
New Resources

Reaxys, the new web interface to access the Beilstein/Gmelin/Chemistry Patent databases, is now available to all University of Michigan students, faculty, and staff. The original access via Crossfire Commander Client will be terminated on December 31, 2010.


Reaxys is the new workflow solution from Elsevier based on the trusted content from CrossFire Beilstein, Gmelin and Patent Chemistry Database. Reaxys integrates reaction and substance data search with synthesis planning. It is an intuitive web-application with powerful and flexible search capabilities, including searching by reaction, substance, and/or numeric property data. Substance searching includes (sub-)structure, generic and R-group searching, molecular formula, name and many more choices. Results - reactions and measured substance data - are presented in easy-to-read tabular views. Intelligent filter and ranking tools allow to determine the most relevant data from a comprehensive data source. The synthesis planner tool also provides the convenience to formulate your own synthetic path by clicking on the reactions you choose.

Access Reaxys

Reaxys is available via internet at Access is restricted to University of Michigan students, faculty, and staff. If you are unable to access the database with your university credential, please contact the Chemistry Librarian Ye Li

Using Reaxys

You may get started with Reaxys by going through the Reaxys Research Guide. Reaxys also offer some learning materials at the Reaxys Training Center. If you need further assistance or would like explore more advanced search strategies such as sub-structure searches, please contact Ye Li to schedule an appointment or workshop for yourself, your group or your class.

Reaxys highlights (Adapted from

Reaxys is designed by chemists for chemists and contains the most relevant reaction and substance data from journals and patent literature. Information on single- and multi-step reactions is deeply indexed and complemented by a synthesis planner to fulfill criteria applicable to a research chemist's needs.

  • Reaxys contains experimental reaction and substance data extracted from trusted literature dating back to 1771, not available elsewhere.

  • Reaxys includes a synthesis planner allowing researchers to identify and combine selected reaction steps to generate the most effective synthesis strategy.

  • Reaxys includes a synthesis planner allowing researchers to identify and combine selected reaction steps to generate the most effective synthesis.

  • It uses "chemistry as organizing principle":   clearly laid out substance or reaction profiles reducing time to get to the relevant results.

  • Experimental procedure texts from patent literature reduce the ned to go to the original document.

  • Intelligent filter and ranking tools allow researchers to find the "best" hits from this extensive source fast.

  • With Reaxys you can link directly to Scopus (cited-by information) and full-text documents (journals and patents) via MGet It to enable further exploration of all the scientific literature.

  • Multiple formats allow to export results, merge with other data or share data with colleagues (DOC, PDF, XLS, SD, RD, RIS, EndNote/Reference Manager).

  • Commercial availabiltiy flags have direct links to chemical directories: synthesize or buy, whichever is more efficient.

  • Reaxys is web-based, intuitive, supports all major browsers and is easy to administer.

  • It is offered via an institution-wide subscription rate with no user limits on access and no software to install.
