Quality Control

Our 6,7-Dichloroquinoline-5,8-Dione is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity assessment, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available for every shipment upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its light-sensitive nature and propensity to be easily oxidized, it is recommended to handle under an inert atmosphere for long-term storage and to minimize headspace in opened containers.
