Degradation & Impurity Profiling
Comprehensive identification and profiling of degradation products and impurities.
Turning Impurity Data Into Quality Insight.
Impurities and degradation products can arise from raw materials, manufacturing processes, formulation components, packaging interactions and product storage. Understanding their origin, behaviour and levels is an important part of pharmaceutical quality assessment.
Our degradation and impurity profiling programs combine analytical method development, stress studies, impurity monitoring and scientific data interpretation to help characterise product quality and support regulatory and quality-risk assessments.
- Degradation Pathway Investigation
- Impurity Identification & Monitoring
- Stability-Indicating Analytics
From Degradation Studies to Impurity Profiling.
Integrated analytical capabilities designed to investigate degradation pathways, identify impurity trends and generate scientifically meaningful data for pharmaceutical quality evaluation.
Understanding Degradation Pathways
Degradation studies help determine how a pharmaceutical substance or product responds to environmental and chemical stresses and provide insight into potential degradation pathways.
Acid & Base Stress
Evaluation of degradation behaviour under selected acidic and basic conditions.
Oxidative Stress
Investigation of susceptibility to oxidation and formation of oxidative degradation products.
Thermal & Humidity Stress
Assessment of product behaviour under elevated temperature and humidity conditions where applicable.
Photolytic Stress
Evaluation of light-induced degradation and formation of photolytic impurities where relevant.
Comprehensive Impurity Profiling
Analytical strategies are used to detect, monitor and characterise impurities associated with pharmaceutical substances and products throughout development and quality evaluation.
- Process Impurities — Identification and monitoring of impurities that may arise from starting materials, intermediates or manufacturing processes.
- Degradation Products — Detection and evaluation of impurities generated through chemical or physical degradation.
- Related Substances — Quantitative and qualitative assessment of related substances using suitable analytical procedures.
- Unknown Impurities — Investigation of previously uncharacterised peaks and impurity patterns for further assessment.
Identification & Characterization Support
When unexpected or significant impurities are observed, targeted analytical investigations can help establish their identity, potential origin and relevance to the product quality profile.
Peak Investigation
Evaluation of chromatographic peaks and impurity patterns requiring further investigation.
Degradation Pattern Analysis
Correlation of impurity profiles generated under different stress and storage conditions.
Analytical Correlation

Specificity
Demonstrating the ability to distinguish the analyte from degradation products, impurities and other matrix components.
Peak Resolution
Achieving chromatographic separation of the principal analyte from relevant impurity and degradation peaks.
Impurity Quantification
Establishing suitable analytical approaches for monitoring specified and relevant unspecified impurities.
Mass Balance
Where appropriate, evaluating degradation behaviour and analytical recovery to support interpretation of stability results.
Method Sensitivity
Assessing analytical capability in relation to applicable impurity reporting and quantitation requirements.
Method Robustness
Evaluating analytical performance under controlled variations in relevant method parameters.
