Quality Control

Our Isorhapontigenin is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) with detailed chromatographic data are provided to guarantee traceability and batch-to-batch consistency.

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 product 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 purity.
