Quality Control

Our Quercetin Hydrate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets stringent specifications for identity, purity, and composition. Certificates of Analysis (COA) documenting results for assay, heavy metals, residual solvents, and microbiological parameters are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, prolonged exposure to light, air, or elevated temperatures should be avoided to maintain stability and potency.
