With Reaxys, research complexity and inefficiency are replaced with the freedom to discover, innovate and drive chemistry research forward.

Reaxys helps organizations by enabling chemists to:

  • Work faster: When nearly 1,700 users competed to solve the same set of chemistry research problems during the 2015 ChemSearch Challenge, a multi-week online competition for chemists. Reaxys users performed twice as fast as users of other chemistry research solutions.
  • More easily find relevant data: Reaxys' smart indexing and streamlined user interface enables even novice or occassional users to retrieve precise data points from within peer reviewed articles, search patents and assess synthesis and property data.
  • Explore and discover more: Reaxys lets users easily control their search results views and see possibilities they may not have considered otherwise.
