Quality Control

Our 7-Chloro-3,4-Dihydro-8-Hydroxy-6-Methoxy-3-Methyl-1H-2-Benzopyran-1-One is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistent chemical identity. Certificates of Analysis (COA) detailing purity, impurities, and physical characteristics are provided with every shipment. We support custom synthesis and purification to meet specific research or cGMP-grade requirements.

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 tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
