What is Reaxys?

Reaxys is an electronic resource that can be used to find references for reactions and properties for chemical compounds. The Reaxys interface pulls information from three databases – Beilstein for organic compounds, Gmelin for inorganic compounds and complexes, and the Patent Chemistry database. You can search Reaxys for references and information on:  

  • Chemical reactions
  • Organic and inorganic substances
  • Measured substance property data (including identification, physical, spectroscopic, bioactivity and ecotoxicological data)

Also included is a synthesis planner that displays multi-step reaction plans with the ability to include alternate options for a synthesis route.

Three ways you can search Reaxys:

  1. Text, Authors and More Search for articles and patents by topic, author, journal citation or patent number.
  2. Substances and Properties Search for particular substances by entering identification or property data, or by drawing the chemical structure or substructure.
  3. Reactions Search for information on reactions by entering specific reaction data or by using the structure drawing software.

Molecular Formula

When searching by molecular formula in Reaxys, you should use Hill Order.  See below for more information on searching for inorganic and organometallic substances.

ChemDraw Ultra is a downloadable application for drawing chemical structures for use in database queries, the preparation of graphics for lab reports and journal articles, providing electronic descriptions of molecules and reactions, and features advanced prediction tools. 

Create tables of structures, identify and label stereochemistry, estimate NMR spectra from ChemDraw structures, obtain structures from chemical names, assign names from structures, and create multi-page documents and posters. 

There is rich polymer notation, generic structure expansion and fragmentation tools. ChemDraw Ultra includes Struct=Name, ChemDraw/Excel, ChemNMR, Stoichiometry Grid, CLogP, tPSA as well as the added capabilities of Chem3D Pro and ChemFinder Std to the ChemDraw Pro application.

With the ChemDraw licence, the MNova Lite download is also available.
