Porton’s highly skilled and experienced analytical R&D teams provide our clients with a full spectrum of RSM/INT/API development, validation, stability study and testing services that fully meet global IND/NDA regulatory expectations and client needs at different stages of drug development.

Method Development, Verification and Validation

• IND/NDA filing readiness; method development report; method monographs; validation reports per ICH guidelines.
  
• Systematic method screening system for rapid establishment of stability-indicating assay/impurity analysis method
• Chiral impurities and purity analysis methods (Chiral Method by HPLC or SFC)
• Counter-ion analysis methods (Titration or IC)
• Analytical methods for (potential) geno-toxic impurities (LC/MS/MS or GC/MS)
• Quick compound-specific residual solvent method development using in-house generic method as starting point
• Water Content by Karl Fischer
• Elemental impurities scanning and control method as per ICH Q3D
• Potency Assay or ID Test by NMR and others for qualitative analysis of impurities or impurity profile comparison work or reference standard characterization, as needed

Stability Study and Evaluation

• Forced degradation and stress tests (Light, acid, alkali, oxidation, high temperature, and high humidity)
• Stability test as per ICH Q1 and NMPA guidelines（40°C /75%RH，30°C /65%RH，25°C /60%RH，5°C）
• Generate protocols and reports applicable to IND filing

Analytical Testing

• Structural elucidation of standards and full characterization of primary standard with chromatographic purity, assay, ROI, LOD, water by KF, residual solvents etc.
• Certificate of Analysis (COA) available
  
• Preparation, structure elucidation and characterization of impurity
• Product release testing and support for process R&D

Quality Control Strategy

• Establishment of impurity control strategy with specification justification
• Research and establishment of quality standards of IND/NDA filing
• Technical support in life cycle management of analytical methods
• QRA, DoE and QbD study support
