Access to SYNTHIA™ Retrosynthesis Software at Queen’s University

We are pleased to share that SYNTHIA™, MilliporeSigma’s retrosynthesis planning software, is now available for use at Queen’s University!

This opportunity was made possible through a generous in-kind contribution from MilliporeSigma made possible by the efforts of the Queen’s University International Student Chapter of the American Chemical Society (Q-ACS). Beginning October 1st, 2025, Queen’s researchers will have access to a free three-month license for SYNTHIA™ (access ends December 31st, 2025), a powerful tool designed to support retrosynthetic investigations and streamline synthetic route design.

We encourage you to register your account in advance of the upcoming training session on October 15th, 2025 (2:00 – 3:00 PM ET).
