Client Needs: A pharmaceutical manufacturer needed to retroactively evaluate a marketed generic API for the presence of N-Nitrosodimethylamine (NDMA) to ensure ongoing product safety and maintain market distribution.
Challenges: The client's existing analytical methods lacked the sensitivity required to detect NDMA at the expected ultra-trace limits. Furthermore, the complex synthesis route involved multiple solvent recovery steps, making it difficult to pinpoint where the contamination was originating.
Solution: BOC Sciences developed a highly sensitive GC-MS/MS method tailored for the API matrix. We conducted a systematic risk assessment across the entire synthetic pathway, analyzing intermediates, recovered solvents, and key process streams to better understand where nitrosamine formation might occur.
Outcome: We successfully identified a specific solvent recovery step as the root cause of the NDMA formation. The client was able to correct the process, eliminate the impurity, and confidently resume API production with verifiable safety data.
Client Needs: A drug developer required quantification of N-Nitrosodiethylamine (NDEA) in a complex solid oral dosage form prior to scale-up manufacturing.
Challenges: The formulation contained proprietary excipients that caused severe matrix suppression during standard LC-MS/MS analysis. This interference masked the target analyte, leading to inconsistent recovery rates and unreliable quantification data that stalled the project.
Solution: BOC Sciences' analytical team developed a novel sample extraction and solid-phase cleanup protocol to isolate the nitrosamine from the interfering excipients. We validated the refined LC-MS/MS method with isotopically labeled internal standards to ensure accuracy, improve reproducibility, and support confident trace-level quantification.
Outcome: The optimized method eliminated matrix effects, allowing for precise quantification of NDEA down to single-digit ppb levels. The client secured the reliable data needed to proceed with scale-up activities safely.
Client Needs: An emerging biotech firm suspected that a secondary amine functional group in their novel small molecule candidate could degrade into a nitrosamine during formulation or storage.
Challenges: The client needed to know if the risk was theoretical or practical before investing heavily in formulation development. They lacked the specialized high-resolution mass spectrometry equipment needed to identify potentially novel, compound-specific nitrosamine degradants.
Solution: BOC Sciences performed predictive risk assessments followed by forced degradation and stress testing. We utilized HRMS to screen for and structurally elucidate any resulting novel nitrosamine species, while comparing degradation outcomes under relevant formulation and storage conditions.
Outcome: Our testing confirmed the susceptibility of the compound under specific conditions. Armed with this knowledge early in development, we guided the client toward a safer synthetic route and alternative excipients, mitigating the risk before costly clinical formulations were produced.
Nitrosamine risk assessment helps development teams identify potential sources of nitrosamine formation in APIs and intermediates, and understand how synthesis routes and storage conditions impact risk. Systematic analysis enables optimized raw material selection and process design, reducing formation likelihood, improving development efficiency, and ensuring safer drug candidates, making it a crucial tool in early-stage drug development.
Identifying potential nitrosamine sources requires combining reaction pathway analysis, chemical structure features, and monitoring key intermediates. Molecular structure prediction, process evaluation, and simulation experiments help locate high-risk steps. BOC Sciences provides professional risk screening services, integrating chemical analysis and process knowledge to quickly identify potential formation points and support effective risk management strategies.
Systematic analysis of possible nitrosamine formation points allows researchers to adjust synthesis routes, raw materials, or storage conditions to reduce risk at the source.
