Quality Control

Our N,N'-Monomethylenebis(Pyridiniumaldoxime) is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and loss on drying to verify moisture content. We provide full traceability and Certificates of Analysis (COA) are available for all shipments to ensure compliance with your research and production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
