Quality Control

Our 1,3-Benzenedisulfonamide is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, to ensure it meets the high standards required for research and industrial synthesis. A Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and consistency.

Storage

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