Quality Control

Our Pyrrolidinium, 1-Ethyl-1-Methyl-, Methanesulfonate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and Karl Fischer titration, to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment. We support cGMP and ISO 9001 compliant manufacturing for critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed under an inert atmosphere such as nitrogen or argon to prevent moisture absorption and degradation.
