Why Reliable Nitrosamine Testing Services in API Are Critical
Unreliable testing can lead to false negatives, inconsistent quantification, and unclear results that interrupt submission timelines. Reliable nitrosamine testing services in API help ensure that your data is accurate, defensible, and aligned with global expectations. With strong testing, teams can detect issues early—long before they affect manufacturing, stability studies, or product quality. When results are precise, it becomes easier to make quick decisions and meet regulatory requirements without unnecessary delays.
Reliable testing also supports patient safety by preventing contaminated products from progressing further in development. With validated workflows and clear data, manufacturers can evaluate their processes and verify that corrective steps are working as intended. ResolveMass Laboratories’ reliable nitrosamine testing services in API are designed to deliver consistent, science-driven results that reduce uncertainty. Our approach removes guesswork and supports smoother, faster regulatory submissions.
Understanding Nitrosamine Risks in APIs
Nitrosamines are highly potent carcinogens that may form through specific reactions during synthesis, formulation, or storage. APIs and drug products are particularly vulnerable to NDSRIs (Nitrosamine Drug Substance Related Impurities), which develop due to structural relationships within the drug substance. Identifying these reaction pathways allows manufacturers to take preventive steps, design safer processes, and strengthen regulatory compliance. Each type of nitrosamine carries a different level of risk, so targeted detection methods are necessary to identify them accurately. With a comprehensive testing plan, companies can detect threats earlier and maintain product quality throughout development.
| Nitrosamine Type | Source | Typical Risk | Detection Method |
|---|---|---|---|
| NDMA | Solvent/amine impurities | High | LC-MS/MS |
| NDEA | Reagents or intermediates | Moderate | GC-MS |
| NDBA | API degradation | High | LC-MS |
| NDSRIs | Drug substance relation | Variable | AI-assisted prediction + LC-MS |

The Regulatory Perspective: Why Timely Testing Matters
Health authorities such as Health Canada, the FDA, EMA, and MHRA now require complete nitrosamine risk assessments and supporting data before any new product approval. When testing is delayed or incomplete, companies face stalled launches, supply interruptions, or unexpected recalls. Timely and reliable nitrosamine testing services in API help you stay ahead of these regulations and avoid issues that can harm brand trust. As global guidelines continue to evolve, proactive nitrosamine management has become essential for maintaining consistent product quality.
| Authority | Regulation | Expected Compliance |
|---|---|---|
| Health Canada | GUI-0104 | Full nitrosamine testing for APIs |
| FDA | Guidance on Control of Nitrosamine Impurities | Mandatory impurity profiling |
| EMA | Nitrosamine Implementation Plan | Stepwise testing and ongoing risk management |
ResolveMass supports companies in navigating these requirements with accurate data, clear documentation, and globally aligned methods. This approach reduces regulatory questions and keeps your submissions moving smoothly.
