Quality Control

Our Disodium 3,7-Diaminodibenzothiophenedisulphonate 5,5-Dioxide is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications. A detailed Certificate of Analysis (COA) is provided with each shipment, guaranteeing traceability and compliance with agreed-upon standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product stability and performance.
