Patcore Inc. (Headquarters: Tokyo) has partnered with Chemical.AI (USA/China), a global leader in AI technology for chemical synthesis route design, to begin domestic provision of the AI retro-synthesis platform "ChemAIRS." ChemAIRS is a platform where AI, equivalent to skilled chemists with over 10 years of experience, can automatically propose complex synthesis routes in just a few minutes. It enables the identification of chirality introduction risks, prediction of side reactions and impurities, and the design of highly feasible routes considering raw material availability, yield, and cost. Additionally, it seamlessly integrates with Chemaxon's "Design Hub," for which Patcore serves as the exclusive domestic distributor, accelerating the DMTA cycle in a one-stop manner. Currently, we are accepting applications for a two-week free trial.
