Quality Control

Our Diammonium Disulphide is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Production adheres to current Good Manufacturing Practices (cGMP) where applicable. Each lot is supported by a comprehensive Certificate of Analysis (COA) detailing key parameters such as assay, identity, and impurity profiles, ensuring it meets the rigorous standards required for industrial and research applications.

Storage

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