Clinical trial material for sterile dosage forms is manufactured at our Irvine (USA) and Hameln (Germany) facilities, serving all the countries where your clinical study is carried over.

Analytical Development

Siegfried understands the critical importance of analytical parameters and controls for effective and robust formulations. Our well-experienced Drug Product Analytical Development team works closely with their Pharmaceutical Development counterparts to ensure our customer’s product is fully supported at every phase in the development process. Modernly equipped, we provide the following range of analytical services to help bring your drug product development project and cGMP manufacture to fruition: 

  • Active ingredient characterization and preparation of specifications (e.g. intrinsic dissolution, particle size, polymorphic form, NMR, IR, UPLC and HPLC-MC, etc.) in close collaboration with the Drug Substance Analytical Development Department.
  • Development of analytical methods and specification preparation for the finished medicinal product 
  • Development on microbio methods
  • Stability screening (incl. forced degradation and photostability investigations) for the selection of the final formulation and the primary packaging material 
  • Validation of analytical methods
  • Support, adaptation and optimization of customers’ methods
  • Analysis of highly-active substances and formulations (cGMP-compliant)
