Quality Control

Our D-Erythro-2-Hexulosonic Acid, 3-Deoxy-, δ-Lactone (9Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and optical rotation measurement, to ensure identity, purity, and chiral integrity. Certificates of Analysis (COA) detailing all specifications and test results are provided with every shipment to support your quality assurance protocols.

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 may affect stability and performance.
