Quality Control

Our Sodium Diprotrizoate is manufactured under strict quality management systems to ensure it meets the exacting standards required for pharmaceutical intermediates. Each batch undergoes comprehensive analytical testing, including identification, assay, and impurity profile analysis via techniques such as HPLC and IR spectroscopy. We provide full traceability and Certificates of Analysis (COA) are available for every shipment to support your regulatory and quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
