Quality Control

Our Sodium Acetrizoate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for pharmaceutical intermediate applications. We provide full traceability and support our customers with regulatory documentation. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available for every shipment upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed after opening to minimize exposure to atmospheric humidity.
