Quality Control

Our Disodium Disulphide is produced under stringent quality management protocols. Each batch undergoes rigorous analytical testing to ensure it meets precise chemical specifications and high-purity standards. A comprehensive Certificate of Analysis (COA), detailing purity, assay, and impurity profiles, is provided with every shipment to guarantee traceability and consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store in a cool, dry, and well-ventilated area. The recommended storage temperature is between 15°C and 25°C. Keep the container tightly sealed when not in use to minimize exposure to atmospheric moisture.
