Quality Control

Our 8-Hydroxy-3,4-Dimethyl-1H-2-Benzopyran-1-One is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) documenting batch-specific results are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Keep away from incompatible materials and sources of ignition. Due to its light-sensitive nature, containers should be opaque or stored in dark conditions.
