Quality Control

Our Sodium Iodide Dihydrate is produced and tested under a rigorous quality management system. We offer grades suitable for industrial and pharmaceutical applications, with testing aligned to relevant pharmacopeial standards (e.g., USP, EP) where specified. A comprehensive Certificate of Analysis (COA) documenting purity, identity, and impurity profiles is provided with each batch to ensure traceability and compliance.

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, minimize exposure to atmospheric humidity during handling. Keep away from strong acids and strong oxidizing agents.
