Quality Control

Our high-purity specialty chemicals are produced under strict quality management protocols. Each batch of 2-[2-[[5,6-Dimethoxy-3-(3-Sulphonatopropyl)-(3H)-Benzoselenazol-2-Ylidene]Methyl]But-1-Enyl]-3-Ethyl-5,6-Dimethylbenzoselenazolium undergoes comprehensive analytical testing, including HPLC for purity and spectroscopic methods for identity confirmation, to ensure it meets exacting research-grade specifications. A detailed Certificate of Analysis (COA) 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 in a desiccated environment to prevent degradation. For long-term storage, consider inert atmosphere conditions.
