Chemlex is devoted to the development and production of fine chemicals and pharmaceutical intermediates in large scale. We take projects from conception through laboratory scale synthesis, analytical validation, process development, pilot plant production, and commercial manufacturing.
Our pilot plant is located in Changzhou which is 70 miles away from Shanghai. The plant consists of 13,000 square feet available space, with modern reactors, filtration and drying equipment. Safety and environmental controls, including water treatment, are implemented throughout the operation.

Pilot plant located in Changzhou, China
Our commercial and cGMP manufacturing facilities are located in Henan, China. The state of art facility is fully US cGMP enabled with controlled/filtered air, over 30 reactors, full suite of filtration and drying equipment.
