Flow Chemistry

Promoting greener, safer and more reliable pharmaceutical innovations 


Established for scaling up the manufacturing process and independent R&D, Asymchem’s flow chemistry have successfully developed platforms for process screening, equipment design and scale-up application after over a decade’s efforts, realizing “end-to-end” continuous green production. Such continuous production which is in compliance with the GMP regulations, has been applied to multiple key intermediates and API commercial projects of innovative drugs.

▲The end-to-end continuous production of the kbeta-lactam key intermediate, independently developed by Asymchem, breaks the limit of conventional batch production mode, which requires a 15-step process and takes 21 days, and is now the shortest synthetic processof MAP worldwide, completing the production in 8 days with much less energy consumption. Besides, the ozonization process of the mode can not only solve the problem of safe amplification, but also avoid using highly polluting and highly toxic reagents. With the production capacity of 8 tons per month, Asymchem can be seen as the industry standard for green safety production.
