Quality Control

Our 2,2'-[(2-Carboxy-p-Phenylene)Bis(Iminovinylene)]Bis[3-Ethyl-4,5-Dihydrothiazolium] Diiodide is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is available upon request to support your quality assurance and regulatory needs.

Storage

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