Integrated chemistry expertise for small molecules

Our integrated development and manufacturing sites in Visp (CH) and Nansha (China) provide advanced chemical synthesis services inclusive of:

  • Hazardous and highly reactive chemicals
  • Organometallic reactions
  • Reductions
  • Oxidations
  • Asymmetric reactions

We also support reactions under special conditions inclusive of low-temperatures, high temperatures and high pressures. 

Synthesis of potent and highly potent intermediates and APIs is fully supported at our Visp location. We provide HPAPI and ADC payload development services across all standard chemical reactions for highly potent applications to 1 ng/m³. Our kilo-lab has full capabilities in sample preparation, ISO and cGMP production for feasibility and early phase clinical projects.

Chemical synthesis technologies are fully supported with extensive process development and intensification. Complementary capabilities in particle engineering – jet milling, spray drying or hot melt extrusion – are employed to prepare drug compounds for formulation to target product profiles.
