Yangzhou Princechem focuses on the development and production of pharmaceutical raw materials, intermediates, and APIs, providing comprehensive CRO, CMO, and CDMO services across the full industry chain. We deliver end-to-end solutions to meet diverse client needs efficiently and reliably.

  CRO Services

We deliver end-to-end technical support from route design to process development, covering compound synthesis, analytical method development, structure confirmation, impurity studies, and quality standard establishment.With advanced analytical platforms such as HPLC, GC, LC-MS, and GC-MS, our laboratories support comprehensive testing of assay, related substances, residual solvents, heavy metals, and genotoxic impurities.Operating under ICH guidelines and cGMP standards, our team has passed multiple audits by domestic and international pharmaceutical companies, demonstrating strong regulatory compliance.

  CMO Serivice

We specialize in the large-scale execution of mature processes, supported by a robust ISO-based manufacturing and quality system. Our custom manufacturing services span APIs and intermediates, with extensive experience in handling highly reactive reagents (BuLi, LiHMDS, NaH), toxic compounds (cyanides, triphosgene), high-temperature/high-pressure catalysis (CO insertion, hydrogenation), and enzymatic catalysis. This deep technical expertise ensures the safe, reliable, and scalable production of complex and demanding projects.

  CDMO Serivice

We have built a multidisciplinary team that integrates strong R&D capabilities with extensive manufacturing experience. Backed by solid chemical expertise and deep process-development know-how, we provide seamless support from laboratory research through full-scale commercialization. Our ISO-compliant kilo lab and pilot plant enable scale-up from kilograms to tons, ensuring products meet the stringent requirements for clinical development and commercial supply. Our services include route design and evaluation, process safety assessment, process development, pilot-scale execution, process validation, end-to-end quality control, and technology transfer—delivering efficient, compliant, and fully integrated CDMO solutions.
Backed by expert teams, advanced facilities, and a rigorous quality system, we deliver reliable one-stop R&D and manufacturing services—cutting costs, accelerating timelines, and ensuring quality to drive the successful commercialization of your products.
