Services - Manufacturing in China

 Manufacturing in China

Our multi-purpose plant was built in 2015 in Jinan, China and is part of the CarboTang Biotech Joint Venture between Biosynth Carbosynth Group and Shengquan Group.

This large-scale manufacturing plant is multi-purpose and flexible with separate chemical and pharma halls, which are built and equipped according to a GMP-like standard (no GMP accreditation).

The plant is constructed to meet EU regulation, including Directive 2011/62/EU, US FDA, CFDA and is compliant with ISO9001:2015 and ISO14001:2015 quality standards.

Scale: from 100s kg to 10 Mt







API manufacturing

Our state-of-the-art GMP-compliant plant in Switzerland performs pilot and production runs in 100 L reactors as well as small scale API manufacturing.

We are a GMP, PMDA and ISO 9001:2015 compliant company. We perform in-process and final control of each API in our Swiss quality control laboratory as we have all modern analytical equipment available in-house. All procedures are validated.

 The route from your need to cGMP product includes strategic and tactical considerations.
