Quality Control

Our Iminodiacetic Acid Disodium Salt Hydrate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets the high-purity standards required for industrial and pharmaceutical applications. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided with every shipment to guarantee traceability and batch-to-batch consistency.

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). This material is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent caking and degradation. Keep away from strong acids and oxidizing agents.
