Quality Control

Every batch of our Bis[2,3-Dihydro-2,2-Dimethyl-7-Benzofurandiazonium] Sulphate is manufactured under strict quality management systems. We ensure high purity and batch-to-batch consistency through rigorous analytical testing, including HPLC, NMR, and spectrophotometric methods. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled room temperature (15-25°C). Due to its hygroscopic and strictly light-sensitive nature, the container must be kept in a dark, moisture-proof environment. Minimize exposure to air and handle under inert atmosphere when appropriate for long-term stability.
