Quality Control

Our Calcium 3-Hydroxy-4-Oxopyran-2,6-Dicarboxylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with key parameters such as assay, impurity profile, and loss on drying. Specifications can be tailored to meet cGMP and other relevant industry standards for pharmaceutical and nutraceutical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and 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 absorption of atmospheric moisture, which may affect product stability and handling properties.
