Quality Control

Our (+)-Catechin Hydrate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, UV), to ensure it meets stringent specifications for research and industrial use. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your quality 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). This material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere); prolonged exposure to air, light, or elevated temperatures should be avoided to maintain stability and potency.
