Analytical and Stability Testing for Injectable Development
Analytical and Stability Testing for Injectable Development
Comprehensive In-House Analytical Capabilities
Oakwood Labs provides a full suite of in-house analytical testing capabilities to support both formulation development and clinical supply manufacturing. By keeping these capabilities internal, we offer rapid turnaround on results and close collaboration between analytical and formulation teams, ensuring faster problem-solving and more efficient formulation development.
Our fully equipped laboratories are located within both the R&D facility and the GMP facility, and include quality control chemistry and microbiology labs. Our expertise spans the entire analytical lifecycle: from initial method development to full method validation for Phase III clinical trials and commercial production, all conducted to globally harmonized standards.
In addition to analytical testing and method development, Oakwood Labs performs ICH-compliant stability studies, covering accelerated, intermediate, and long-term conditions, to ensure product quality throughout shelf life.
For the development of microsphere-based products, our typical characterization analysis focuses on four key tests, designed to optimize performance, stability, and release profiles:
| Analysis | Method |
| Drug Load (% drug encapsulated) | HPLC Assay |
| Particle Size and Volume Distribution | Laser Diffraction |
| Residual Solvent | Gas Chromatography |
| In Vitro Release | Shaker Bath or USP II/IV Apparatus, HPLC Assay |
