Quality Control

Our production of 2,4-Bis[2-[4-(Dimethylamino)Phenyl]Vinyl]-1-Ethylpyridinium Iodide adheres to stringent quality protocols to ensure batch-to-batch consistency and high performance for critical applications. Each lot is characterized using advanced analytical techniques to confirm identity, purity, and functional properties. A comprehensive Certificate of Analysis (COA) detailing specifications such as HPLC purity, absorbance/fluorescence profiles, and moisture content is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from incompatible materials.
