Quality Control

Our production of 4,5-Dihydroxy-2-(3,5,7-Trihydroxy-4-Oxo-4H-1-Benzopyran-2-Yl)Benzenesulfonic Acid adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure compliance with exacting standards. A comprehensive Certificate of Analysis (COA), detailing all specification parameters, is provided with each shipment to guarantee traceability and batch-to-batch consistency for our global B2B clients.

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 (moisture-sensitive) nature, the container must be kept sealed immediately after use to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
