Implementation of QbD Concepts
-
Final Process Development:
-Ideally Performed Before PhIII or Reg Campaigns; Reduce PMI
-Quality Improvement
-Plant Fitness Assessment
-
Justification of the Specs of RSM and Intermediates:
Study the formation, fate, and purge of impurities from the RSM synthesis, and establish RSM specs based on the purge studies of these impurities in downstream processes.
-
Quality Risk Assessment:
Comprehensive process characterization via DoE studies or OVAT studies, including FMEA, probability, impact, detectability, PAR, and NOR.
Life Cycle Management
-
R&D in Commercial Campaign:
- Cost Saving, Time Saving, and EHS Purposes (such as reducing PMI) and Troubleshooting
- Based on the Current Process, Optimize the Process to Improve Yield and Efficiency (such as replacing solvents, simplifying work-up, recycling materials, and other methods)
- 2nd Generation Process R&D
-
We Manage the Product Lifecycle from Three Different Aspects:
- Continuous Cost Improvement
- Sustainable Supply Chain Management
- Capacity Planning
