Quality Control

Our production of Calcium Bis[2,4-Diaminobenzenesulphonate] adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR for identification, and titration for assay confirmation, to ensure it meets precise customer specifications. Certificates of Analysis (COA) documenting all critical parameters are provided and can be tailored to support compliance with cGMP, ISO, and other relevant regulatory frameworks for industrial and research use.

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 absorption of atmospheric moisture. For long-term storage, consider using desiccants or maintaining the material under an inert atmosphere to mitigate potential oxidation.
