Nitrosamines have emerged as one of the most pressing challenges in the pharmaceutical industry. Classified as probable human carcinogens, these compounds can form through multiple pathways during drug manufacturing, storage, or analysis. Their mutagenic potential has prompted global regulators to mandate stringent limits, comprehensive testing, and rigorous quality controls.
While raw materials and intermediates are often seen as the major contributors to nitrosamine contamination, one often-overlooked source is solvents. During highly sensitive LC-MS (Liquid Chromatography–Mass Spectrometry) analysis, even trace levels of nitrite impurities in solvents can compromise results.
Recognizing this hidden risk, ADVENT has launched its LC-MS Premium (Nitrite-Free) Solvent range — a decisive step toward enhancing accuracy, compliance, and patient safety.
Why Nitrite-Free Solvents Matter
Nitrites act as precursors to nitrosamines. When present in solvents, they can:
React with secondary or tertiary amine drug substances, forming nitrosamines in situ.
Interfere with LC-MS analysis, creating false positives, false negatives, or retention time shifts.
Undermine the sensitivity and accuracy of analytical data, misleading entire research strategies.
Trigger compliance issues, recalls, financial losses, and brand damage if undetected.
In short, the absence of nitrite contamination is critical for precise nitrosamine detection and for maintaining regulatory confidence.
ADVENT’s LC-MS Premium (Nitrite-Free) Solvents
After extensive research and purification, ADVENT introduces Acetonitrile, Methanol, Isopropyl Alcohol, and Water in its new LC-MS Premium Grade, all guaranteed nitrite-free by design.

Implications for the Industry
By eliminating nitrite interference at the solvent level, ADVENT is addressing a gap that directly affects:
Drug discovery & development – Ensuring robust, reproducible data.
Pharmaceutical quality control – Strengthening compliance with nitrosamine regulations.
Research integrity – Empowering scientists with confidence in their LC-MS results.
As Dr. Rashmi Ranjan Mohanty, Director-Technical at ADVENT, emphasized, “We are not just supplying solvents — we are empowering scientists with the confidence to generate accurate, reproducible data, free from hidden risks.”
Conclusion
The fight against nitrosamines requires vigilance at every stage of the pharmaceutical value chain. Solvents, though often underestimated, can play a decisive role in ensuring accuracy and safety. With the launch of LC-MS Premium (Nitrite-Free) Solvents, ADVENT sets a new benchmark for purity, compliance, and reliability. This innovation is more than a product launch — it is a commitment to precision, responsibility, and patient safety. By redefining solvent standards, ADVENT is helping the pharmaceutical industry move forward with confidence, accuracy, and care.
