In my previous blog, I spoke about the FDA recall of angiotensin II receptor blockers like losartan. This recall was due to the presence of genotoxic nitrosamines.
Is a proactive approach the way to mitigate risk?
Recently, the FDA has re-issued the 2018 guidance to industry, “M7(R1) assessment and control of DNA reactive (mutagenic) impurities in pharmaceuticals to limit potential carcinogenic risk”. Is this going to help? Or should we have a higher focus of qualitative analysis up front?
Companies need to take a look all facets of their supply chain and manufacturing process. They should be able to ensure they can control the active pharmaceutical ingredients (APIs) throughout the process, whether they do it in their own facility or it is outsourced.
How are they going to do this?
Why you need a control strategy
A control strategy is a planned set of controls derived from current product and process understanding that assures process performance and product quality (ICH Q10, Ref. 8).
A control strategy can include, but is not limited to, the following:
How to ensuring better data, by seeing it all
Work previously presented by Prof. Sörgel, at the Institute for Biomedical and Pharmaceutical Research, Nuremberg, Germany on the benefits of this workflow is that with SWATH® Acquisition you are creating a digital record of all the analytes in the sample.
This approach shows:
Watch out for our next blog where we examine some of the analytical challenges of these molecules.You can learn more about how LC-MS/MS solutions can identify, quantify and monitor the required levels of nitrosamine impurities by accessing technical notes and a webinar addressing the characterization and quantification of the genotoxic impurities.

This is part two of an ongoing blog series on genotoxic analysis. Read part one: “What have we learned from the nitrosamine crisis?” and part three: “Developing a method for nitrosamine analysis in pharmaceutical products“.

In biopharmaceutical development, sequence variants (SV) are considered an inherent risk of producing complex proteins in living systems. Sequence variants are unintended changes to the amino acid sequence of a biotherapeutic and can be caused by errors in transcription or translation in the host cell, or cell culture and process conditions. Detailed analysis of SVs is important in process and product development to ensure the drug’s safety and efficacy. Even low‑level sequence variants can have significant implications for product quality, safety, and efficacy, making their accurate detection and characterization a critical requirement across development, process optimization, and regulatory submission.
CE‑SDS remains a cornerstone assay for characterizing fragmentation, aggregation, and product‑related impurities in therapeutic proteins. UV detection has been the long‑standing standard. However, it frequently struggles with baseline noise, limited sensitivity for minor fragments, and subjective integration.
At SCIEX, innovation doesn’t stop at instruments; it extends to how you interact with your LC-MS/MS or CE systems every day. That’s why we’re excited to introduce the SCIEX Now spring 2026 improvements: a set of meaningful enhancements shaped directly by your feedback.
