Quality Control

Our 3,3',4,5'-Tetrahydroxystilbene is produced and tested under a strict quality management system to ensure batch-to-batch consistency and high purity suitable for research and industrial use. We provide comprehensive analytical data, including HPLC purity, identity confirmation (IR, NMR), and residual solvent analysis. Certificates of Analysis (COA) are available for every batch upon request.

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