As global regulatory bodies tighten scrutiny on pharmaceutical impurities, Nitrosamine NDSRI Impurity Testing in 2025 is set to become more critical than ever. For pharmaceutical companies aiming to stay ahead of Health Canada, FDA, and EMA guidelines, understanding the cost, turnaround time, and submission readiness of Nitrosamine NDSRI Impurity Testing is essential.
At ResolveMass Laboratories Inc., we specialize in advanced analytical services that ensure your Active Pharmaceutical Ingredients (APIs) and drug products meet strict nitrosamine limits—including the detection of nitrosamine drug substance-related impurities (NDSRIs). In this guide, we provide a comprehensive overview of what your team needs to plan for successful testing and regulatory submission.
Why Nitrosamine NDSRI Impurity Testing Is Essential in 2025
Nitrosamines, particularly NDSRIs, are emerging as a major concern due to their genotoxic potential. Regulators have mandated targeted testing for these substances in:
- Small molecule APIs
- Finished dosage forms
- Products with secondary or tertiary amines
- Legacy drugs already on the market
ResolveMass Laboratories uses validated LC-MS/MS and GC-MS platforms for sensitive Nitrosamine NDSRI Impurity Testing, aligned with Health Canada and international guidelines. Learn more about our methods.
What Are NDSRIs and Why Are They Unique?
NDSRIs are a subset of nitrosamines that can form during synthesis or storage when specific functional groups interact with nitrosating agents. They are more structurally complex and often require custom synthesis of reference standards, making their identification and quantification challenging.
ResolveMass has extensive expertise in:
- Custom NDSRI synthesis
- Risk-based impurity profiling
- Threshold of toxicological concern (TTC) assessments

Turnaround Time (TAT) for Nitrosamine NDSRI Impurity Testing
At ResolveMass Laboratories, we prioritize fast, accurate, and compliant testing. Our typical turnaround time for Nitrosamine NDSRI Impurity Testing is:
- Standard TAT: 7–10 business days
- Expedited Testing: 48–72 hours (rush surcharge applies)
Our lab is equipped with redundant instrumentation to ensure minimal downtime, even for urgent requests. View our testing capabilities.
Preparing for Regulatory Submission in 2025
1. Compile a Comprehensive Risk Assessment
Start with a risk-based evaluation of your drug substance synthesis pathway to identify potential NDSRI formation.
2. Engage a GLP-Compliant Lab
Only partner with labs like ResolveMass that provide GMP/GLP-aligned reports accepted by Health Canada and FDA.
3. Ensure Proper Method Validation
If no compendial method exists, method validation is critical for submission acceptance.
4. Submit a Detailed Testing Package
ResolveMass offers submission-ready documentation for both generic and branded drug makers. Learn more.
5. Stay Updated on Limits and Thresholds
New AI-generated TTC values for complex NDSRIs are being released. Keep your safety evaluations aligned.
