Nitrosamine Impurity Testing for regulatory confidence.
Stabicon operates a dedicated nitrosamine testing capability covering risk assessment, ultra-trace quantitation and confirmatory analysis of N-nitrosamine impurities – including small-molecule nitrosamines (NDMA, NDEA) and complex Nitrosamine Drug Substance-Related Impurities (NDSRIs).
Our methods are developed and validated to detect impurities at parts-per-billion (ppb) to parts-per-trillion (ppt) levels using LC-MS/MS and GC-MS/MS, with workflows aligned to ICH M7(R2), US FDA and EMA expectations.

Why Nitrosamine Control Matters
Nitrosamines are potent, highly regulated genotoxic impurities.
Following global recalls of sartans, ranitidine and metformin, regulators now require manufacturers to evaluate every drug substance and drug product for the potential presence of N-nitrosamine impurities and to control them below strict acceptable-intake limits.
Because nitrosamines can form from secondary or tertiary amines reacting with nitrosating agents – in the API, excipients, packaging or even during storage – control requires both a structured risk assessment and analytical methods sensitive enough to detect impurities at trace levels.
Stabicon supports manufacturers across the complete nitrosamine control workflow: structured risk evaluation, sensitive confirmatory testing, NDSRI characterisation and mitigation strategy – generating data that withstands regulatory scrutiny.
Our Nitrosamine Capabilities
A complete nitrosamine programme – assessment to confirmation.
We perform a structured risk evaluation across the API synthetic route, excipients, water, recovered solvents, packaging and manufacturing process to determine whether nitrosamines could plausibly form or carry over.
Assessment covers
- Route-of-synthesis and reagent review
- Excipient and packaging interaction risk
- Cross-contamination and carry-over risk
- Degradation and storage-induced formation
- NDSRI predisposition for amine-containing APIs
