Quality Control

We supply Sodium Iodide in various grades, including Industrial, Technical, and high-purity Pharmaceutical grades. Our products undergo rigorous quality testing to ensure compliance with industry standards and customer-specific requirements. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are available upon request. We can align with relevant pharmacopeial standards such as USP, EP, or ACS where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent absorption of moisture from the air, which can lead to caking or decomposition.
