Asymchem Agrees to Acquire Snapdragon Chemistry

February 12, 2022

Cooley advised Asymchem, a Chinese-based contract development and manufacturing company serving the global pharmaceutical and biotech industry, on its definitive agreement to acquire Snapdragon Chemistry, a US-based chemical technology company. Partner Yiming Liu led the Cooley team.

As a result of the transaction, Asymchem will significantly expand its footprint in the US, offering customers a seamless path from preclinical process R&D through commercial current good manufacturing practice (cGMP) production. Snapdragon will operate as a stand-alone Asymchem division, and continue with its ongoing lab and manufacturing facility expansion for additional capacity to support larger, pilot-scale manufacturing in Waltham, Massachusetts.

"We believe continuous flow manufacturing is a revolutionary technology and represents the future of pharmaceutical production, not only generating advantages to process safety and cost, but also bringing tremendous environmental benefits," Hao Hong, chairman and CEO of Asymchem, said in a news release. "Asymchem has been deeply committed to flow chemistry technology development and its application expansion in the pharmaceutical industry for more than a decade. We are excited that this strategic acquisition will further strengthen our capabilities in continuous manufacturing, as well as broadening our service scope and client pool."
