Quality Control

Our Afzelin is produced and tested under a rigorous quality management system. Each batch is analyzed to ensure high purity and consistency, with specifications suitable for research and development applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your project requirements.

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 exposure to air and moisture.
