Quality Control

Our 7-o-(β-Hydroxyethyl)Quercetin is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets stringent specifications for nutraceutical and research applications. Certificates of Analysis (COA) documenting purity, residual solvents, and heavy metals are available upon request to support your regulatory and quality assurance needs.

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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which may affect stability and handling properties.
