Quality Control

Our 4-Chloromethyl-7,8-Dimethyl-Chromen-2-One is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity assessment and NMR/IR for structural confirmation, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing batch-specific results are provided with each shipment.

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 sealed to prevent exposure to atmospheric moisture. Keep away from incompatible materials.
