Quality Control

Our Diammonium Imidodisulfate is manufactured under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed against stringent in-house specifications, which typically include identity confirmation, assay, and impurity profile checks. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your technical requirements.

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 nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product quality and handling properties.
