Quality Control

Our Pinostilbene is produced under strict quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity verification and identity confirmation by spectroscopic methods. We provide full traceability and Certificates of Analysis (COA) are available for all shipments to ensure compliance with your research and manufacturing standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 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.
