Quality Control

Our Gadobenic Acid Disodium Salt is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, ICP-MS for elemental impurities, and specific tests for residual solvents and related substances, ensuring compliance with ICH Q3 guidelines. A comprehensive Certificate of Analysis (COA) detailing all specifications and test results is provided with every shipment to guarantee traceability and consistency for your pharmaceutical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is kept tightly sealed in a low-humidity environment to prevent degradation. For long-term storage, consider using desiccants.
