Quality Control

Our Cirsilineol is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity verification and spectroscopic methods (IR, NMR, MS) for structural confirmation, to ensure it meets the high standards required for research and commercial use. A detailed Certificate of Analysis (COA) is provided with every shipment.

Storage

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