Quality Control

Our 3-Ethyl-2-[3-(3-Ethyl-3H-Benzoselenazol-2-Ylidene)Prop-1-Enyl]Benzoselenazolium Iodide is produced and handled under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity assessment and spectroscopic methods (NMR, IR) for structural confirmation, to ensure consistent performance and high chemical integrity for research and industrial applications. Certificates of Analysis (COA) detailing batch-specific results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed in a desiccated environment and handled under low-light conditions to prevent degradation.
