Quality Control

Our 7,8-Dihydroxy-3,4-Dimethyl-2H-Chromen-2-One is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its property of being easily oxidized, long-term storage is recommended under an inert atmosphere (e.g., nitrogen or argon). Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Keep away from incompatible materials.
