Quality Control

Every batch of 2,1,3-Benzoselenadiazole-4-Sulfonyl Chloride is produced and tested under strict quality management protocols. We ensure compliance with relevant research and development standards. Comprehensive analytical data, including HPLC purity and spectroscopic identification, is documented. A Certificate of Analysis (COA) is provided with each shipment to guarantee traceability and product integrity.

Storage

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