Flow Chemistry

Sustainable Access to Drug Substance

Over the last ten years, Asymchem’s Chemical Engineering Lab (CEL) has led our flow chemistry service solutions and developed multiple platforms and processes. The resulting mastery of “end-to-end” continuous flow production allows our team of specialized scientists and engineers to fabricate new reactors and develop robust processes to match reaction requirements. These solutions offer customers multiple advantages including improved safety and efficiency, space savings, increased production capacity, and paired with in situ reaction monitoring.

To date, CEL has developed platforms for process screening, equipment especially designed for process validation and prototype reactors. Applying these advances, we’ve been able to easily judge flow reaction feasibility, transfer new technology to production, and scale-up applications quickly — all while applying GMP requirements.
