Quality Control

Our hydrogen 2-[2-[[5,6-dimethyl-3-(3-sulphonatopropyl)-3H-benzoselenazol-2-ylidene]methyl]but-1-enyl]-5,6-dimethyl-3-(3-sulphonatopropyl)benzoselenazolium, sodium salt is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and spectroscopic methods for identity confirmation, to ensure it meets precise customer specifications. A comprehensive Certificate of Analysis (COA) detailing purity, absorbance/fluorescence profiles, and other critical parameters 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 nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption. For long-term stability, consider storage under inert atmosphere.
