Quality Control

Our Cirsimarin is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity verification and spectroscopic methods for structural confirmation (IR, NMR, MS). We provide full traceability and Certificates of Analysis (COA) are available for all shipments, ensuring compliance with research-grade standards.

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, long-term storage under an inert atmosphere (e.g., argon or nitrogen) is recommended for optimal stability.
