Quality Control

Our α-Glycerophosphoric Acid Disodium Salt is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets the required specifications for identity, purity, and composition. Certificates of Analysis (COA) are provided with every shipment, detailing key parameters such as assay, impurity profile, and moisture content. We can supply material compliant with various pharmacopeial standards (e.g., USP, EP) upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product stability and handling properties.
