Quality Control

Our Sodium Iodide is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets the required specifications for purity, identity, and impurity profiles. We can supply material compliant with various pharmacopeial standards (e.g., USP, EP, BP) upon request. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; containers must be kept tightly sealed to prevent absorption of moisture and degradation.
