Quality Control

Our A-D-Glucopyranuronic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including identification (IR, NMR), purity assay (HPLC), and specific tests for related substances and residual solvents, to ensure it meets stringent specifications for research and industrial use. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect stability and purity.
