Founded in August 2007, Shanghai Maxchemco is a R&D contract research company located at the East China University of Science & Technology. Its predecessor, Sunnytech Limited, started research and technology transfers in both microbiological and chemical areas in 2000.  During this seven year period, we commercialized many of the processes and technologies developed, helping a variety of pharmaceutical companies achieve industrial scale production.  This year, Sunnytech, after  7 years of successful business, split into two more specialized and efficient companies: Maxchem (chemical) and Mexcell (biological).  We can now provide our clients with a more comprehensive range of services including intermediates production and biological fermentation. 

As a company integrating research, production, sales and services, Maxchemco endeavors to provide customized services in drug discovery, chemical/pharmaceutical intermediates, and bulk drug production to international pharmaceutical, chemical, and biotech companies. Its sister company, Mexcell Biotech, provides fermentation and semi-synthetic products.
