Innovation in retrosynthetic analysis

Reaxys has partnered with the most innovative AI companies, Iktos and Pending.AI, to develop best-in-class predictive retrosynthesis models based on Reaxys’ high-quality reaction data. Our customers can select either of the retrosynthesis solutions that best fits their needs to:

Ideate quickly: Access predicted routes in minutes, along with experimental procedures, to quickly assess route feasibility and take it to the lab.
Unlock synthetic challenges: Get innovative disconnections supported by literature references; validate new ideas with the latest research.
Control selectivity: Apply chemo-, regio- and stereoselective strategies to support retrosynthesis of drug-like molecules.
Create custom routes: Define intermediaries to include or exclude; add or remove steps to tailor routes to your specific chemistry needs.
Control costs: Design routes while limiting the cost of building blocks; all routes end in commercially available starting materials.
Upskill teams: Access literature references that informed predicted steps, including conditions and experimental procedures.

The best-in-class AI for chemical synthesis now available via API

Computational chemistry and data science teams can now use Reaxys Predictive Retrosynthesis’ intuitive API to integrate the predictive models into chemistry ecosystems. Run searches for hundreds of compounds at the same time to accelerate projects and seamlessly incorporate into workflow systems.
