Innovation in retrosynthetic analysis

Reaxys and Pending.AI teams have collaboratively developed the award-winning Reaxys Predictive Retrosynthesis solution. Routes can be generated within minutes, helping accelerate synthesis planning for novel compounds and route optimization for known compounds.

  • Ideate: Access chemically feasible and innovative predicted routes, along with published routes

  • Review and edit: Access literature references that informed predicted steps, including conditions and experimental procedures add or remove steps to tailor routes

  • Control cost: Easily select the routes to be taken to the lab as they always end in commercially available starting materials

AI and the largest database of chemical reactions yields robust predicted retrosynthesis routes

Retrosynthetic analysis once relied solely on a chemist’s expertise and time. The award-winning Reaxys Predictive Retrosynthesis changes that paradigm. It augments your knowledge with robust predicted routes by applying AI to the world’s largest database of chemical reactions. Get faster answers for a broader range of molecules with Reaxys Predictive Retrosynthesis.
