Quality Control

Every batch of our 7-Hydroxy-2-(p-Hydroxyphenyl)-2,3-Dihydro-4H-1-Benzopyran-3-One is produced and tested under a strict quality management system. We guarantee high purity and batch-to-batch consistency through advanced analytical techniques including HPLC, GC, and NMR. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to ensure it meets your specific R&D or production requirements.

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 sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from incompatible materials.
